Well, the bootstrap was all langs (minus ada due to not having ada
installed) and ppc32 multilibs were built.  Plus the testsuite run
with RUNTESTFLAGS="--target_board=unix'{-m32,-m64}{-mlra,-mno-lra}'"

I would have bootstrapped -m32 except the machine I used lacked 32-bit
gmp, mpfr, mpc and I was lazy.

I guess I should at least build glibc.
