Well, that "t-spe" file is not being included at all for our target triplet
right now; it only gets referenced for "powerpc-linux-eabispe" targets as
per "src/gcc/config.gcc".
Furthermore, the Debian PowerPCSPE port does not want any of the stuff in that
file, as it's all multilib stuff that doesn't apply to e500 anyways.
So the MULTILIB_OSDIRNAMES value in "t-spe" needs to be changed to "eabispe"
upstream as a bugfix, but that is not applicable to the Debian e500 port.
I suppose in theory PPC EABI is better than PPC SYSV and if I'd have given it
a bit more thought I might have tried to build the port based on "eabispe" in
the first place, but that's water under the bridge at this point. Even still,
we wouldn't want the multilib stuff anyways.
Cheers,
