re PR bootstrap/3163 ([3.3 Only] gcc/aclocal.m4 mmap test fails on UnixWare 7.1.1)

	PR bootstrap/3163
	* aclocal.m4 (AC_FUNC_MMAP_ANYWHERE, AC_FUNC_MMAP_FILE): Delete.
	(gcc_AC_FUNC_MMAP_BLACKLIST): New.
	* configure.in: Check for sys/mman.h and mmap in AC_CHECK_HEADERS
	and AC_CHECK_FUNCS lists, respectively.  Use
	gcc_AC_FUNC_MMAP_BLACKLIST, not AC_FUNC_MMAP_ANYWHERE nor
	AC_FUNC_MMAP_FILE.
	* configure, config.in: Regenerate.
