This patch enables building glibc-2.2.5 using TCC and GNU Make 4.x and Mes C Library.
* Makefile: Do not assemble from stdin, use file indirection.
* Makefile: Add new target: install-lib-all.
* Makefile: Avoid building stub DOC.
* [_LIBC_REENTRANT]: Add missing guarding.
* [MES_BOOTSTRAP]: Disable some GCC extensions.
* [MES_BOOTSTRAP]: Add missing GCC div/mod defines.
Upstream status: Not presented upstream.
