gc_pthread_redirects.h: Generalize test to use GC_PTHREADS.
* include/gc_pthread_redirects.h: Generalize test to use GC_PTHREADS.
* linux_threads.c (WRAP_FUNC(pthread_join)): Conditionalized on
GC_FREEBSD_THREADS, handle strange interaction between system
pthread implementation and boehm-gc signal-handler architecture.
* tests/test.c (main): Conditionalized on GC_FREEBSD_THREADS,
set stack.
* include/private/gcconfig.h (configuration keyed off FREEBSD):
Define SIG_SUSPEND, SIG_THR_RESTART. Do not define
MPROTECT_VDB when GC_FREEBSD_THREADS is defined.
