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

     3 reporter_comment="This is a sample config file for Freescale e500v2 processors (e.g., MPC8548,
     4 MPC8572). It uses eglibc (for e500/SPE patches) and a recent gcc (4.6.0,
     5 for e500v2 DPFP support) and will generate appropriate dual-precision
     6 floating point instructions by default.

     8 Note: If building a Linux kernel with this toolchain, you will want to make
     9 sure -mno-spe AND -mspe=no are passed to gcc to prevent SPE ABI/instructions
    10 from getting into the kernel (which is currently unsupported). At this time,
    11 the kernel build system properly passes those two options, but older kernels
    12 were only passing -mno-spe by default."
