[Bug c++/33960] New: [4.3 Regression] r129030 breaks -fopenmp -static compile of tramp3d-v4

["rguenth at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

Starting with r129030 tramp3d-v4 segfaults on startup if compiled statically
with -fopenmp.  This can be reproduced with the preprocessed testcase from
http://www.suse.de/~rguenther/tramp3d/tramp3d-v4.ii.gz (x86_64) and compiling
with -fopenmp -static (optimization does not change the effect).

        * gcc/gthr-posix.h (__gthread_cond_broadcast, __gthread_cond_wait,
        __gthread_cond_wait_recursive): Add to extend interface for POSIX
        conditional variables. (__GTHREAD_HAS_COND): Macro defined to signify
        support of conditional variables.
        * gcc/gthr-posix95.h (__gthread_cond_broadcast, __gthread_cond_wait,
        __gthread_cond_wait_recursive): Add to extend interface for POSIX
        conditional variables. (__GTHREAD_HAS_COND): Macro defined to signify
        support of conditional variables.
        * gcc/gthr-single.h (__gthread_cond_broadcast, __gthread_cond_wait,
        __gthread_cond_wait_recursive): Add to extend interface for POSIX
        conditional variables.
        * gcc/gthr.h: Update comments to document new interface.
        * libstdc++-v3/include/ext/concurrent.h (class __mutex,
        class __recursive_mutex): Add new method gthread_mutex to access
        inner gthread mutex.
        [__GTHREAD_HAS_COND] (class __concurrence_broadcast_error,
        class __concurrence_wait_error, class __cond): Add.
        * guard.cc (recursive_push, recursive_pop): Delete.
        (init_in_progress_flag, set_init_in_progress_flag): Add to
        replace recursive_push and recursive_pop.
        (throw_recursive_init_exception): Add.
        (acquire, __cxa_guard_acquire, __cxa_guard_abort and
        __cxa_guard_release): [__GTHREAD_HAS_COND] Use a conditional
        for synchronization of static variable initialization.
        The global mutex is only held briefly when guards are
        accessed. [!__GTHREAD_HAS_COND] Fall back to the old code,
        which deadlocks.
        * testsuite/thread/guard.cc: Add new test. It deadlocks with the
        old locking code in libstdc++-v3/libsup++/guard.cc.
