Hello Christopher,

Trying to duplicate your cross compiler, here is what I get:
# ECONF_EXTRA="--without-x --enable-languages=c,c++ \
--with-cpu=ep9312 --with-float-abi=softfp --with-fpu=maverick" \
crossdev -S armv4t-maverick-linux-gnueabi

I'm not sure what I missed?

NO doubt I did not add these patches. Could you explain in a little
bit more detail, just how to perform any additional patches?
