We build gcc after clang, and extract libgcc libraries and libstdc++
headers from gcc and place them in the clang installation directory in a
way that clang favors before it searches the system for libraries and
includes.
Its only purpose is to disable PGO. Where that was not already explicitly done,
or irrelevant (because the directory only contains python), I disabled it in
moz.build.
As part of this move, HOST_NSPR_MDCPUCFG needed to be changed to get the quoting right.

When switching between Gtk+3 and Gtk+2, config.cache will contain a PKG_CONFIG
that may not be suitable for the build:
- after a Gtk+2 build, config.cache will point to the system pkg-config, which
doesn't like the pkg-config files in the Gtk+3 tooltool package.
- after a Gtk+3 build, config.cache will point to the Gtk+3 tooltool package's
pkg-config, which is likely not there in a Gtk+2 build.
Setting PKG_CONFIG avoids all config.cache considerations altogether, so set it
appropriately for both cases.
Some mozconfigs don't include mozconfig.linux*, and don't get gtk-related
definitions, so move them in a separate mozconfig. To avoid having two
files, one for 32-bit builds and one for 64-bit builds, rely on the
includer to set PKG_CONFIG_LIBDIR appropriately.
At the same time, move all the --enable-default-toolkit=cairo-gtk2 in that
new file in the case the gtk3 package wasn't pulled from tooltool.
Write a mozconfig fragment which makes the rust toolchain
provided by tooltool available for linux builds.
Use linux64 mozconfigs to enable rust for official builds of
that target. These aren't used outside of automation builds,
so including rust there will verify code on check-in without
requiring developers to install rust.
LTO changes in GCC5 make it break the assumptions made in the test-ctors
source. The simplest and more correct thing to do is to just force the
test files never to be built with LTO. They are meant to have a particular
layout that LTO might break at any time anyways.
There are, sadly, many combinations of linkage in use throughout the tree.
The main differentiator, though, is between program/libraries related to
Gecko or not. Kind of. Some need mozglue, some don't. Some need dependent
linkage, some standalone.
Anyways, these new templates remove the need to manually define the
right dependencies against xpcomglue, nspr, mozalloc and mozglue
in most cases.
Places that build programs and were resetting MOZ_GLUE_PROGRAM_LDFLAGS
or that build libraries and were resetting MOZ_GLUE_LDFLAGS can now
just not use those Gecko-specific templates.
'make check' is somewhat special in that we want to trigger testers
before it finishes. Since moving sendchange into mach is difficult and
'make check' may be going away in the future anyway, just pull it out
for now.
Also remove the MOZ_AUTOMATION_*_SENDCHANGE flags since we aren't using
them.
