These paths can contain spaces, particularly if they point into
${HOME}/.mozbuild on Windows. If people are bold enough to use the
Windows packages from llvm.org, the LLVM packages are installed by
default into C:\Program Files\LLVM, so paths from there would contain
spaces as well.
Procedural macros for rust are compiled as dynamic libraries.
The compiler subsequently loads those libraries at runtime
when it compiles crates which make use of them.
We pass the generic LDFLAGS to our linker wrapper which ensures
cargo links static libraries with the correct flags. However
this also means that any final system dependency libraries
end up linked into the procedural macro dynamic libraries
whether they use them or not.
When building on macOS 10.7, this causes a SIGTRAP when dlopen
calls CFInitialize for system libraries like Cocoa off the main
thread. We believe this is a macOS bug, reported fixed in macOS 10.9.

Work around the issue by stripping those libraries and Frameworks
from the linker flags we pass to cargo. We could do a more careful
job of parsing and removing all -framework and -lfoo arguments
inside the linker script, but since this is a temporary issue
while we're using older build machines, I thought just stripping
them once in the build system was simpler.

For linking static libraries, rustc will use whatever `cc` it finds (or
the equivalent on Windows). For our purposes, however, `cc` is not what
we use to link and we may have additional options we would like to pass
to the linker.
To do this, we need to tell Cargo about our alternate linker (currently
only used for target compilations, on the theory that the host compiler
rustc finds is probably good enough) and we also need to pass our linker
options into the process. We do this with environment variables, which
is not a great solution, but works surprisingly well.
This alternate linker is disabled for ASan builds due to peculiar
crashes when running Rust build scripts and for Windows, because we
don't do any interesting cross-compiling there.
This change paves the way for injecting target- or host-specific
environment variables for a particular `cargo build` invocation. Doing
this is not strictly necessary: all of our current `cargo build`
invocations use mostly target-specific environment
variables (e.g. PKG_CONFIG_ALLOW_CROSS). But separating things out
makes the code notationally cleaner and also avoids weirdness when
target==host.
Instead of using the -i flag to clean out the entire set of environment
variables, we explicitly just clear out the variables that are affected by
32- vs 64-bit builds in vcvars.bat. This still allows cargo to use it's
internal autodetection to do host/target builds as it wants when cross-compiling,
but also allows other things that rely on include directories and so on to
work properly.

This change brings Cargo closer to what our C/C++ build already does,
and some forms of Cargo failure are only diagnosed when you pass
`--verbose`, so let's eliminate that extra step for people.
For people working on Rust code, compiling in debug mode (Cargo's "dev"
profile) is convenient: debug assertions are turned on, optimization is
turned off, and parallel compilation inside of rustc itself can be
used. These things make the build faster and the debugging experience
more pleasant.
To obtain that currently, one needs to --enable-debug at the Gecko
toplevel, which turns on debug assertions for the entire browser, which
makes things run unreasonably slowly. So it would be desirable to be
able to turn *off* debug mode for the entirety of the browser, but turn
on debug mode for the Rust code only.
Hence this added switch, --enable-rust-debug, which does what it
suggests and defaults to the value of --enable-debug. For our own
sanity and because we judge it a non-existent use case, we do not
support --enable-debug --disable-rust-debug.
This commit moves symbol dumping to the compile tier, to be run via "syms"
targets. Tracking files are used for the sake of incremental builds, because
dump_syms may genearate multiple outputs whose paths are not known ahead of
time.
Minimal changes to symbolstore.py are made here. More extensive
simplifications will be made in a future commit on the basis of symbolstore.py
handling one file at a time.

This creates "syms" targets that depend on the corresponding "target" for
directories containing shared libraries or programs. These targets are added
to the main compile graph in automation, and can be invoked through a special
"symbols" target. A future commit will use these targets to dump symbols for
shared libraries and programs during the compile tier.

This prevents the variables set in vcvars.bat from causing build failures when
cargo tries to process build scripts in an environment where the default rust
toolchain doesn't match the MozillaBuild shell (in terms of 32-bit or 64-bit).

The code doing that was already excluding OSX, so we obviously don't
need it on OSX. On FreeBSD, afaict, USDT (userspace dtrace) probes don't
require that extra ELF object. Solaris presumably does, but the 6 years
old bug 702179 says it's not been working for that long, and configure
doesn't support Solaris targets anyways.
Keeping this build system code working past the changes coming in bug
1262241 is not guaranteed and can't be tested, so I'd rather get rid of
effectively dead code rather than trying to maybe not break it while
moving it.

sutagent is no longer built or used; devicemanagerSUT is completely
unused. After this change, devicemanagerADB is the only implementation of
devicemanager, and test harness options like --dm_trans are eliminated.
Although bug 1322703 is backed out, we can remove -FS options to build SIMPLE_PROGRAM.

We've been using -Z7 to make MSVC emit CodeView debug info directly in
the object files instead of in PDB files because sccache can't cache
PDB files if the same one is written to by multiple compiles, which
was previously happening in our build system, and was hard to override
in the NSS build. Now that those are fixed this should work fine.
This adds a bit to the compile rule to remove the PDB file before
compilation, since sccache won't cache a compilation if the PDB file
it is supposed to generate already exists (for the aforementioned reason).
