Using --enable-e500-double for a non-e500 target will produce a broken
compiler.  So if you want e500 double code to work at all, try the
powerpc-eabispe target.  (Or else pass -mabi=spe explicitly.)

It is also known that all the insn patterns for e500 are only expected to work
for big-endian.  In general little-endian Power is hardly tested at all, but
the SPE case is specifically expected to be broken.
