[PATCH] patchelf: Add patch to handle large files

[Richard Purdie <richard.purdie@linuxfoundation.org>]

There were "maximum size exceeded" errors from patchelf when processing
qemu-native. There is an issue open for this upstream, add a patch 
proposed there for this issue. "32" was increased to "64" to handle our 
qemu-ppc binary.
