This adds a configure check for std::thread. This is needed because std::thread is not available on some systems, like some versions of mingw and DJGPP. This also adds configury to make sure that a threaded gdb links against the correct threading library (-lpthread or the like), and passes the right flags (e.g., -pthread) to the compilations. gdb/ChangeLog 2019-09-30 Tom Tromey <tom@tromey.com> * acinclude.m4: Include ax_pthread.m4. * Makefile.in (PTHREAD_CFLAGS, PTHREAD_LIBS): New variables. (INTERNAL_CFLAGS_BASE): Use PTHREAD_CFLAGS. (CLIBS): Use PTHREAD_LIBS. (aclocal_m4_deps): Add ax_pthread.m4. * config.in, configure: Rebuild. * gdbsupport/common.m4 (GDB_AC_COMMON): Check for std::thread. gdb/gdbserver/ChangeLog 2019-09-30 Tom Tromey <tom@tromey.com> * acinclude.m4: Include ax_pthread.m4. * config.in, configure: Rebuild.
