+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.

+        * Makeconfig (+common-includes): Define.
+        (+includes): Use @$(common-objpfx)includes.
+        * Makefile (postclean): Remove includes and includes.mk.
+        * Makerules ($(common-objpfx)includes.mk): Include and create
+        includes.mk.  Create includes.
