commit 59d9f1d6983fc9b606a1f9214fb817efe3d6cff8
Author: Daniel Jacobowitz <dan@codesourcery.com>
Date:   Thu Apr 8 16:48:17 2010 -0700

    Shorten build commands
    
    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.
