[patches] [PATCH] Fix EGLIBC build with -Os

[Aurelien Jarno <aurelien@xxxxxxxxxxx>]

EGLIBC (and GLIBC) currently fails to build with -Os, because some
functions like fstatat64() are not inlined. This results in a failure
are link time, as those functions are only available statically in 
libc_nonshared.a.

When linking against libc.so, the /usr/lib/libc.so helper scripts takes
care of linking with this static library. In order to build libc.so with
-Os, it is also needed to link with libc_nonshared.a. That's the purpose
of the patch below.

Tested successfully on amd64, the testsuite shows no regressions when
building with -Os instead of -O2. I am sending this patch to the
EGLIBC mailing list as I am not sure such a patch would be accepted in
GLIBC, while it is surely something wanted in EGLIBC. Reducing the 
memory footprint is one of the goal of EGLIBC.

        * Makerules ($(common-objpfx)libc.so): link with
	$(common-objpfx)libc_nonshared.a.
