 Hopefully one day the plugin will work with an unpatched gcc, but for the
 moment a small patch needs to be applied.  Configure gcc with your favorite
 options and also with --enable-lto.  Build gcc and install it somewhere.
+If you don't have libelf installed then the build will fail, because gcc's
+LTO code makes use of it, see
+  http://gcc.gnu.org/wiki/LinkTimeOptimization#Building_the_branch
 
 Darwin special: the gcc configure script thinks darwin doesn't support dynamic
 libraries and concludes that plugins won't work.  Delete or improve the check.
