* locale/programs/xmalloc.c: Test _LIBC as well as STDC_HEADERS.
	* locale/programs/ld-collate.c (collate_finish): Use error_at_line
	instead of error_with_loc.

	* locale/weight.h: Use u_int32_t instead of u32_t.
	* string/strxfrm.c: Likewise.

	* string/strxfrm.c: Find weight.h in ../locale; don't #include
	"localeinfo.h".
	* string/strcoll.c: Likewise.

	* locale/programs/simple-hash.c, locale/programs/simple-hash.h,
 	locale/programs/xmalloc.c, locale/programs/xstrdup.c: Helper functions
 	for locale related programs.
