libg/eglibc: add updated eglibc 2.15

Includes a patch to remove __builtin_expect test:

In eglibc-2.15, the build breaks in configure while testing
for the existance of __builtin_expect. It fails with newer
versions of gcc.

This patch is a modification of an upstream change in glibc
mainline (to be 2.16) to fix the following error:

[CFG ] checking for __builtin_expect... no
[ERROR] configure: error: support for __builtin_expect needed

     1 older verisons of glibc would build dl-sysdep as shared-only and dl-support as
     2 static-only.  alpha hooks in a cache variable via dl-auxv.h.  newer versions of
     3 glibc build dl-sysdep as both shared and static which means we now have symbol
     4 duplication for static builds with dl-sysdep and dl-support.  since dl-sysdep
     5 is both shared/static, there is no point in hooking dl-support anymore, so we
     6 can punt it.
