re PR libgcj/23367 (_Jv_FindMethodInCache is not thread-safe)
PR libgcj/23367:
* include/jvm.h (_Jv_FreeMethodCache): Declare.
* java/lang/natClass.cc (MCACHE_SIZE): Conditional on HAVE_TLS.
(struct _Jv_mcache): Likewise.
(method_cache): Likewise.
(_Jv_FindMethodInCache): Do nothing unless TLS is available.
(_Jv_AddMethodToCache): Likewise.
(_Jv_FreeMethodCache): New function.
* java/lang/natThread.cc (finish_): Call _Jv_FreeMethodCache.
* aclocal.m4, configure, include/config.h.in: Rebuilt.
* configure.ac: Invoke GCC_CHECK_TLS.
