When malloc is not available, this will set #define malloc rpl_malloc
which is implemented only inside libcheck, and not everything will link
to libcheck.
We don't really need to care too much about how malloc is implemented
and we don't care about platforms that don't implement malloc.
This brings us up-to-speed with the latest compatibility code from upstream
check git. For completeness, we do all the checks that upstream check does, but
we skip the snprintf/vsnprintf code because it's not straightforward (involves
running code and that is bad for cross-compilation) and not necessary for the
platforms we support anyway.
If someone really wants this, they can uncomment this and copy the relevant
checks from the check git repository.

It was always evaluating to false, so clock_gettime.c was always being
included into libcheck. This breaks building on Hurd and causes us to
always override clock_gettime() even when it is available.

With XCode 8, clock_gettime will be incorrectly detected as being
available regardless of what OS X version we're targetting because the
symbol is available in the .tbd library as a weak symbol.
See: https://github.com/Homebrew/homebrew-core/issues/3727#issue-170086273
It's only starting from macOS 10.12 that clock_gettime is actually
available, so we can unconditionally disable it when targetting older
versions. We cannot simply do AC_CHECK_FUNCS with -Wl,-no_weak_imports
because the autoconf check does its own prototype declaration that
doesn't trigger that compiler flag.

Reintroduced patches:
* Make sure that fail_if(1) actually fails
from commit 9f99d056a2
New patches due to updated libcheck (based on 0.9.14):
* Checks in m4/check-checks.m4 to cater for new dependencies
* Conditional compile-time compat POSIX fallbacks for libcheck
* Avoid relative paths for libcheck header files
* Make timer_create() usage depend on posix timers, not librt
* Rely on default AX_PTHREAD behavior to allow HAVE_PTHREAD to be used
when checking for types and functions (like clock_gettime())
* Avoid double declaration of clock_gettime() when availabe outside of
librt by making compat clock_gettime() declaration conditional
* check 0.9.9 renamed _fail_unless() and 0.9.12 later renamed it again
to _ck_assert_failed(), so ASSERT_{CRITICAL,WARNING}() now calls this
function
* Remove libcheck fallback infrastructure for malloc(), realloc(),
gettimeofday() and snprintf() since either they appear to be
available or they introduce even more dependencies.
The result is an embedded check in gstreamer that has been tested by
running check tests in core, -base, -good, -bad, -ugly and rtsp-server
on Linux, OSX and Windows.
Fixes https://bugzilla.gnome.org/show_bug.cgi?id=727826
Without using AC_INCLUDES_DEFAULT explicitly,
certain platforms will complain that the header
was found, but not usable by the compiler.
This happens for instance on Solaris where certain
headers are needed to pull in proper defines.
Also upgrade to newer autoconf syntax and use proper quoting.

This is how we do it in the other modules, and gets rid of the annoying
dirty status for common when doing git status (at least once you clean
out the old files from there).
Original commit message from CVS:
this patch fixes arts and artsd compilation problems. this is necessary for make
dist to work. i know plugins are being moved, though, this needs to be ported to
the -plugins module.
* experimental and broken selection now use GST_CHECK_FEATURE, for what it's worth
* crucial fixes to arts m4's that need backporting to autostars and -plugins
* make gst-feature less frantic in reporting missing plugins
* cleanups and misc arts fixes
