Subject: [PATCH] fix: m4 recipe - strip GL_CFLAG_GNULIB_WARNINGS typedefs +
 fix_types.h

Root cause: gnulib configure bakes raw typedef statements
(typedef long unsigned int size_t; etc.) into the generated
Makefile's GL_CFLAG_GNULIB_WARNINGS variable. These break
shell command parsing when expanded on recipe lines.

Fix:
1. Strip raw typedefs from all generated Makefiles after configure
2. Provide fix_types.h with guarded typedefs for size_t, ptrdiff_t,
   off_t, wchar_t, ssize_t, time_t
3. Force-include fix_types.h via CPPFLAGS to work around the
   cross-compiler's GCC built-in stddef.h ordering issue

Also: comprehensive upstream relibc comparison and import plan
