gcc: Add 'mcf' thread model support from mcfgthread
This patch adds the new thread model `mcf`, which implements mutexes
and condition variables with the mcfgthread library.
Source code for mcfgthread is available at <https://github.com/lhmouse/mcfgthread>.
config/ChangeLog:
* gthr.m4 (GCC_AC_THREAD_HEADER): Add new case for `mcf` thread
model
gcc/ChangeLog:
* config/i386/mingw-mcfgthread.h: New file
* config/i386/mingw32.h: Add builtin macro and default libraries
for mcfgthread when thread model is `mcf`
* config.gcc: Include 'i386/mingw-mcfgthread.h' when thread model
is `mcf`
* configure.ac: Recognize `mcf` as a valid thread model
* config.in: Regenerate
* configure: Regenerate
libatomic/ChangeLog:
* configure.tgt: Add new case for `mcf` thread model
libgcc/ChangeLog:
* config.host: Add new cases for `mcf` thread model
* config/i386/gthr-mcf.h: New file
* config/i386/t-mingw-mcfgthread: New file
* config/i386/t-slibgcc-cygming: Add mcfgthread for libgcc DLL
* configure: Regenerate
libstdc++-v3/ChangeLog:
* libsupc++/atexit_thread.cc (__cxa_thread_atexit): Use
implementation from mcfgthread if available
* libsupc++/guard.cc (__cxa_guard_acquire, __cxa_guard_release,
__cxa_guard_abort): Use implementations from mcfgthread if
available
* configure: Regenerate
