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

     5     Rules.mak: Rearrange appending UCLIBC_EXTRA_CFLAGS to CFLAGS
     6     
     7     UCLIBC_EXTRA_CFLAGS is currently added before the OPTIMIZATION flags
     8     and OPTIMIZATION is chosen to be Os by default. But in OE we pass the optimisation
     9     flags through UCLIBC_EXTRA_CFLAGS but they are not effective since -Os is
    10     specified at last. So we need to change the order of these option flags
