powerpc-*-rtemsspe* would be OK.

powerpc-*-eabisimspe* is pretty ugly though.

It is obvious but if powerpc-*-XXXspe* is the pattern, then the
spe cases need to be above in all configure switches. I hate to
mention it but a fair number of odd RTEMS issues turn out to be
from inadvertent side-effects when cleaning up configure switches.
