eglibc: Add patch to limit gcc commandline output.

* This patch reduced the size of do_compile of eglibc from 12M to 5.4M
  and the build time for eglibc improved a bit too

* The patch applied to 2.9,2.10 and 2.11

+Source: http://sourceware.org/ml/libc-alpha/2010-03/msg00064.html
+
+This patch scratches an itch.  Each individual gcc command in the
+glibc build is over 1K, which means it takes up a good chunk of my
+terminal.  Most of that is include paths.  Any version of GCC new
+enough to build glibc supports response files, which were added in
+2005.  So use a response file for the static list of include paths.
+Now the build commands are a lot shorter, and easier to use when
+developing glibc.
+
+Tested on x86_64-linux-gnu.  Please apply if acceptable.
