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
