[patch libgcc]: Fix PR c++/57440

[Kai Tietz]

Hi,

this patch adds for Windows targets the define
_GTHREAD_USE_MUTEX_INIT_FUNC, which is necessary as pthread-emulation
for those targets are just handling pthread_mutext_init,
othread_mutex_destroy proper.

ChangeLog libgcc

        PR c++/57440
        * gthr-posix.h (_GTHREAD_USE_MUTEX_INIT_FUNC): Define for native windows
        targets.

Patch passed already regression-test for x86_64-unknown-linux-gnu.
Test for i686-w64-mingw32 is still running (with posix-threading
model).  Ok to apply this patch after last test passes?

Regards,
Kai

As Jonathan said in comment #12 of http://gcc.gnu.org/PR57440 , the
right place for this #define is
libstdc++-v3/config/os/mingw32*/os_defines.h.
