It appears an unpatched version of gcc-4.8.0 builds on Ubuntu-12.10 64-bit with
../gcc-4.8.0/configure \
 --target=avr \
 --enable-languages=c,c++ \
 --disable-nls \
 --disable-libssp \
 --with-dwarf2 \
 --prefix=$HOME/avr-rtems

The two following configurations do not build on Ubuntu-12.10 64-bit:
"can't find limits.h in the include path"
../gcc-4.8.0/configure \
 --target=avr-rtems \
 --enable-languages=c,c++ \
 --disable-nls \
 --disable-libssp \
 --with-dwarf2 \
 --prefix=$HOME/avr-rtems

"cannot compute suffixes"
../gcc-4.8.0/configure \
 --target=avr-elf \
 --enable-languages=c,c++ \
 --disable-nls \
 --disable-libssp \
 --with-dwarf2 \
 --prefix=$HOME/avr-rtems

Next steps: plan to attempt to build avr-libc, configuring the build and
install directories such that it increases the chances it can be used to build
RTEMS.
