It was setting ATTRIBUTE_ALIGNED_MAX which hasn't been used for 6 years
since 590a7be0e60f (bug 556455) removed its only consumer.

Skipping them saves 1.5-2.0s from configure during an artifact build
on Windows.

Currently, the build scripts enable AltiVec unconditionally on all ppc*
targets. However, there some ppc* targets which do not support AltiVec
instruction set extensions, these are often embedded systems like the
PowerPC e500 or similar which have their own type of instruction set
extensions like SPE. Trying to enable Altivec support on these targets
results in a compiler error, hence we need to add an autoconf test for
AltiVec support before trying to enable it on ppc* targets.

Subtly, as toolkit/moz.configure happens before toolchain tests, we
can't set MOZ_SERVO_LIBS from there. And toolkit/moz.configure is
not always included either, making things awkward to do in python
configure.
OTOH, there's only one place where MOZ_SERVO_LIBS is used, and the
corresponding setup can actually be done there (in moz.build) instead.
I think we shouldn't shy away from moving things this way.
This patch introduces a small change in behavior: we now unconditionally
require libffi > 3.0.9 when using system ffi, rather than accepting 3.0.9
when using GCC, as 3.0.10 was released 5 years ago, and should be widely
available.

Also, now that we're using modern C++11 compilers, we can just rely on
static_assert, instead of the pile of macros used in the autoconf test.

Now that we compile with cargo, we don't have fine-grained control over
the build flags used via environment variables detected in configure or
set in config.mk. We should just remove that dead code so nobody trips
over it.
Functions deprecated in GTK3 are often used for compatibility with GTK2
builds.

The only use of this variable is to override NSINSTALL, and its value is
the same as NSINSTALL_PY.
While here, remove the outdated NSINSTALL_NATIVECMD that was used for
pymake.

Nothing is using MAKE in old-configure, and it was not AC_SUBST'ed, so
we don't need to set it when it's not set in the environment already.

Since bug 1259382, CC and CXX are always set, so we can stop
falling back to cl on Windows, and clang on OSX in compiler-opts.m4.
Also, we were actively rejecting GCC on OSX because it was based on
GCC 4.2 and known to be broken, but that test predates our requirement
for more recent versions of GCC, which would fail configure anyways.
So just remove that GCC test. Building with a modern GCC from macports
or wherever might actually work anyways.
Finally, remove target bit-width mismatch with the compiler as it's
handled in python configure since bug 1288313.

The base compiler check in python configure does some preprocessing,
which ensures the compiler works to some extent. Autoconf used to have
a more complete test, doing a compile/link. We do have plenty of tests
afterwards that do that anyways, but it's better if we fail early if
the toolchain fails somehow.
This refactors try_compile such that the *_compiler variable themselves
can be used to trigger compiler tests. Eventually, we'll want something
similar for preprocessing and possibly other invocations.
This also removes similar tests from build/autoconf/toolchain.m4 and
old-configure.in.
