Subject: [PATCH nolibc 50/61] tools/nolibc: add the nolibc subdir to the common Makefile

From: Willy Tarreau <w@....eu>

The Makefile in tools/ is used to forward options to the makefiles
in the various subdirs. Let's add nolibc there so that it becomes
possible to make tools/nolibc_headers_standalone from the main tree
to simply create a completely usable sysroot.
