It was added for llvm-symbolizer, and at the time, it was required.
However, since [1] (shipped in llvm 12), llvm-symbolizer, msdia140.dll
is not used by default, only when passing the -dia command line option,
which we don't use.

There is only one place where it's used:
config/check_vanilla_allocations.py, which is only executed from
js/src/build/Makefile.in on the condition that the build is targeting
Linux and not LTO. But the LTO test is actually outdated, because we
don't build with `-flto`, but `-flto=thin`, so the exclusion doesn't
work anymore.
There is however no AC_CHECK_PROG, and we currently rely on NM to be
given, or fall back to "nm", which works in most cases, except LTO with
clang. It works on CI because in LTO builds we explicitly set NM to
llvm-nm (which can output symbols from LLVM bitcode objects), but we
could also do that automatically.
So we add a full detection of nm/llvm-nm to python configure, and limit
it to Linux, since we only ever use it there.

Otherwise we won't package the necessary libraries, which leads to
peculiar runtime failures.

This patch is not ideal: if would be better to do the defaulting in
`toolkit/moz.configure`, but doing it there runs into problems with base
toolchain configurations, as the clang there is not new enough. So we
have this, doing everything with environment variables, which is easily
turned on or off, depending on the needs of the specific configuration.
The `mozconfig.no-compile` change is not really needed, as the wasm
sandboxing detection bits are not conditional on
`--enable-compile-environment`. Those bits should be, and I will tackle
doing that after the holidays.

Now that everything is lined up nicely, we don't need those anymore.
We can fill cargo-linker.bat with HOST_LINKER and HOST_LINKER_LIBPATHS,
which, unfortunately, can't be used as is, so we add a variant for
substitution in .bat files.

Last attempt, a few years ago, blatantly failed because nautilus (the
GNOME file manager) can't start PIE executables, which look like shared
libraries, and that it thus considers not being executables.
Downstreams don't actually have the problem, because users won't be
launching Firefox from a file manager, but for mozilla.org builds, it is
a problem because users would download, then extract, and then likely
try to run the Firefox executable from a file manager.
So for mozilla.org builds, we still need to find a way around the
nautilus problem.
A .desktop file could be a solution, but .desktop files have not
actually been designed for this use case, which leads to:
- having to use an awful one-liner shell wrapper to derive the path
to the executable from that of the .desktop file,
- not even being able to associate an icon,
- the .desktop file not being copiable to a location where .desktop
files would normally go, because it would then fail to find the
executable.
Another possibility is to go back to using a shell wrapper, but that's
not entirely appealing.
What we chose here is similar, where we have a small `firefox` wrapper
that launches the real `firefox-bin` (which is still leftover from those
old times where we had a shell wrapper, for reasons).
The small `firefox` wrapper is a minimalist C executable that just
finds the path to the `firefox-bin` executable and executes it with the
same args it was called with. The wrapper is only enabled when the
MOZ_NO_PIE_COMPAT environment variable is set, which we only take into
account on Linux. The variable is only really meant to be used for
mozilla.org builds, for the nautilus problem. Downstreams will just pick
the default, which is changed to build PIE.
On other platforms, PIE was already enabled by default, so we just
remove the --enable-pie configure flag.

At the same time, we make it actually do something on spidermonkey
builds. We also add an environment variable alternative, that we use
in mozconfig.stdcxx, allowing for mozconfig.no-compile to override it
and avoid configure failures on e.g. artifact builds.

We want most builds to be actually using sccache, so we include
mozconfig.cache from mozconfig.common. However, since the --with-ccache
configure option doesn't exist on non-compile jobs (e.g. artifact
builds), we move to using the CCACHE environment variable instead, which
allows us to unset it in mozconfig.no-compile.
And since mozconfig.no-compile is always included where no_sccache is
set, we can remove that variable.

LLVM_CONFIG, per the contents of toolkit/moz.configure, is tied to
--enable-stylo, but it currently is set on all types of builds. It
currently happens to work, but it's actually not meant to, and sure
enough, the fix for bug 1374727 exacerbates that.
So we create a new mozconfig.stylo file that enables stylo and sets
LLVM_CONFIG, such that only build types that do enable stylo have
LLVM_CONFIG set.
