	* io/ftwtest-sh: Only invoke ld.so if it exists.
	* math/Makefile (LDLIBS-*): Change from libm to math/libm to get
	static tests to link.  Honour $(omit-long-double-fcts) == yes.
	* math/libm-test.c (test_single_exception): The argument to
	fetestexcept is `int' not `fexcept_t'.
	* shlib-versions: Recognize sparc64.
	* signal/signal.h: Add typedef for stack_t.

	* stdio-common/_itoa.c: Defaulting UMUL_TIME==UDIV_TIME is broken.
