Initial Package Version: 2.3.3-lfs-5.1
Upstream Status: not submitted
Origin: based on a Rock Linux patch for 2.3.4/gcc-3.4 by Rene Rebe
Description:

 When building a cross-toolchain for the lfs-5.1 versions on a host
which is running an older version of gcc, libgcc_eh is not built,
causing glibc to fail to link.

 I don't really understand what this does, but it works well enough
to cross-compile a kernel.
