* sysdeps/ieee754/ldbl-opt/math_ldbl_opt.h [__ASSEMBLER__]: Don't

	include problematic headers for assembler.

	* Makerules ($(+sysdir_pfx)sysd-rules): Don't emit m_%.c rules,
	instead emit m_%.o compilation rules from s_%.? source files.
	* math/Makefile ($(objpfx)m_%$o: s_%.c): New rule using o-iterator.
