commit 90a0154d6ef1effe64c199eb61a06430199aaa91
Author: Eric Blake <address@hidden>

    Make bootstrap easier on Solaris.
    
    * bootstrap: Add GNULIB_SRCDIR.  Useful when a wrapper script
    gnulib-tool exists earlier on the path to work around /bin/sh
    failure in parsing $GNULIB_SRCDIR/gnulib-tool.
