FWIW the procedure you describe on
http://www.smartcontroller.com.au/~angelo/rtems/BuildGCC.html

can be significantly slimed down and speed up by removing c++ and f77
from --enable-languages.

--enable-languages=c is sufficient to build GCC to bootstrap GCC
cross-toolchains like the RTEMS GCCs.

If you further want to speed this up, and do not plan to use this GCC
for other purposes but to bootstrap cross-GCCs, you can use "make all"
instead of "make bootstrap" (This avoids building a "staged" GCC).
