	* math/Makefile (libm-calls): Change s_ldexp to m_ldexp.
	* Makerules ($(+sysdir_pfx)sysd-rules): Emit pattern rules for m_%.[Sc]
	from sysdeps/.../s_%.[Sc] with commands $(+make-include-of-dep).
	(+make-include-of-dep): New canned sequence.

	* stdlib/canonicalize.c (__realpath): Check for malloc failure.
