	Portability improvements, e.g., libmudflap/15293.
	* configure.in: Look for glibc extension functions.  Look for
	support of -f{function,data}-sections.  Look for more headers.
	Create testsuite/mfconfig.exp.  Correct more "test x.." thinkos.
	* Makefile.am: Use $(SECTION_FLAGS).  Collapse piecemeal-compiled
	mf-hooks* into usual single object per source.
	* mf-hooks*.c: Remove all #if WRAP_foo conditionals.
	* mf-hooks2.c: #include a bunch more system headers.  Define strnlen
	if system doesn't provide one.
	* mf-hooks3.c (struct pthread_info): Add stack_*_alloc fields.
	(pthread_create): Use it to properly GC dead thread stacks.
	* mf-runtime.c (__mf_violation): Correct snprintf type warning.
	* testsuite/Makefile.am: Stop generating site.exp.
	* testsuite/mfconfig.exp.in: New file.
	* testsuite/config/default.exp: Load new mfconfig.exp.
	* testsuite/lib/libmudflap.exp (libmudflap-init): Add extra libraries.
	(prune_gcc_output): Add glibc static linking warnings.
	* testsuite/libmudflap.*/*frags.exp: Enumerate needed -lmudflap* libs.
	* testsuite/libmudflap.c/pass46-frag.c: Ditto.
	* configure, Makefile, aclocal.m4, config.h.in, testsuite/Makefile.in:
	Regenerated with autoconf 2.57 and automake 1.7.
