[oe] Next set of EP93xx patches

[Marcin Juszkiewicz]

Here I am with another set of patches to make EP93xx cpus working better
in OpenEmbedded.

This time I merged glibc 2.6.1 and binutils 2.18 patches done by Hasjim
Williams and changed a bit Ångström configs for building with Maverick
tuning enabled.

After rebuilding whole rootfs I got system which works and even gives
proper output from 'openssl speed md5' command.
