You need the patch attached to

Why? 

--target=powerpc-rtems
does everything you need.

Besides this I strongly recommend to keep rtems-4.7 toolchains separate
from rtems-4.6 toolchains, i.e. to install them into a different prefix
and using a different target tuple.

ie. I recommend to configure binutils and gcc w/
--prefix=/opt/rtems-4.7 --target=<target>-rtems4.7
