Another obstacle:

The ${target} in case of powerpcspe is powerpc-unknown-linux-gnuspe, but t-spe is
only included in one place (src/gcc/config.gcc):

powerpc-*-eabispe*)
        tm_file="${tm_file} dbxelf.h elfos.h freebsd-spec.h newlib-stdint.h rs6000/sysv4.h rs6000/eabi.h rs6000/e500.h rs6000/eabispe.h"
        extra_options="${extra_options} rs6000/sysv4.opt"
        tmake_file="rs6000/t-spe rs6000/t-ppccomm"
        use_gcc_stdint=wrap
        ;;

which looks quite bsd specific and doesn't match our target. How about including
rs6000/t-spe instead of rs6000/t-linux at the place where currently only
rs6000/t-linux is added?

I can send a patch after my test run is finished.
