the build without libgcj and it tries to build zlib internally without
that switch. Check recent build logs from LFS, you should see what I mean.
I read this:[http://gcc.gnu.org/install/configure.html]
And according to bruce's investigation, zlib is only used by java and
lto(gcc's link runtime optimization, a new feature added in gcc-4.5,
depends on libelf). we don't use java and lto in lfs.
