avr-gcc should build out of the box.  No patches are needed.  What problems did
you encounter?

--with-avrlibc is mainly an optimization thing to endure basic float arithmetic
from libm.a is used and not the one from libgcc.a.

Again, avr-gcc should build out of the box, no matter how --with-avrlibc is set
and no extra patches are needed.
