Bug 1500504 added a version check for the SDK, but it only does the
check if --with-macos-sdk is used. We should also check the version when
using the default SDK.
Note that this means we now set MACOS_SDK_DIR to be the default SDK even
if it wasn't set explicitly from --with-macos-sdk

If mozbuild parsing fails due to a missing file (eg: a file not existing
in UNIFIED_SOURCES), then no Makefiles are written out, but
config.status exists. This would cause mozbuild to think that configure
doesn't need to run, and rely on make to perform the backend-out-of-date
check in rebuild-backend.mk. Unfortunately since no Makefiles were
written, the make command fails immediately and no attempt is made to
re-create the backend. Note that this is only a problem if the first
mozbuild parsing from a clobber build fails, otherwise there is
typically a top-level Makefile from a previous build to call into (at
which point make can determine it is out-of-date, and re-invoke itself).
The fix is to have the RecursiveMake backend re-use the same logic that
was introduced into mozbuild for alternate backends, and remove
rebuild-backend.mk. This way, mozbuild can always determine if the
backend needs to be regenerated, even if the initial parsing failed.
Test code was also relying on rebuild-backend.mk to generate the
TestBackend, but moving backend_out_of_date() into MozbuildObject allows
this code to be shared.

Interestingly, the change makes one configure test have a different
result (localeconv ends up being found when it used not to be found),
but the result of that check is actually not used on Windows because we
set HAVE_LOCALECONV manually.

This imports the changes from wheezy-lts (http://deb.freexian.com/extended-lts/)
and creates a package we install in the debian7-based images (with a
modified version number to work around bug #1419577.
This leaves out debian7-raw and debian7-packages as unpatched, because
of the chicken-and-egg problem.

When cross-building with clang, we use `--target` with a target that is
derived from the configure target, with the vendor removed. So for
`configure --target=aarch64-unknown-linux-gnu`, we use
`clang --target=aarch64-linux-gnu`.
Then, clang itself looks for tools as `$target-$tool` first, then
`$tool`, which means for the assembler, it's looking for
`aarch64-linux-gnu-as` before `as`, but not
`aarch64-unknown-linux-gnu-as`.
Building GNU as with `--target=aarch64-unknown-linux-gnu` creates the
`aarch64-unknown-linux-gnu-as`, but we really want `aarch64-linux-gnu`,
so we adjust the target in the binutils build script.

As of clang 8, llvm-config doesn't return all flags clang was built
with, and omits some flags that do impact the libclang ABI,
-stdlib=libc++ being one of them (it might well be the only one).
Building clang with LLVM_ENABLE_LIBCXX=ON does build it with
-stdlib=libc++, but is unrelated to whether or not libc++ is built and
shipped with clang, which still happens without it.
So while versions older than clang 8 are not really affected, it doesn't
hurt to build clang without -stdlib=libc++ (especially when it
currently only applies to the clang used to cross build android with
PGO, not even the other android cross builds), in preparation for
switching to clang 8.

There is no concern that the Android NDK clang may not support it, as
the flag was added in clang 2.9. The flag is also not supported with
GCC, which is not ideal, but we already crossed that bridge at least
with -gcc-toolchain added in extra_toolchain_flags, which is not
supported by GCC either.

We shouldn't pass those flags when building C. It doesn't matter /too/
much currently, but will in a subsequent change, which will introduce
a C++-only flag in stlport_cppflags.
