	* locale/loadlocale.c (_nl_load_locale): If LOCALE/LC_* is a
 	directory, open LOCALE/LC_*/SYS_LC_* instead.

	* stdio/fpioconst.c, stdio/fpioconst.h, stdio/gmp-impl.h,
	stdio/gmp.h, stdio/longlong.h, stdio/mp_clz_tab.c,
	stdio/gen-mpn-copy: Files moved to stdlib.
	* stdio/Makefile: All mpn stuff moved to stdlib/Makefile.
	* stdio/printf_fp.c: Use ../stdlib to find fpioconst.h and gmp
 	headers.
	* stdlib/strtod.c: Don't use ../stdio to find fpioconst.h and gmp
 	headers.
