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.
