gcc 8 has declared powerpc*-*-*spe* obsolete, needing --enable-obsolete

[Mark Millard]

https://gcc.gnu.org/gcc-8/changes.html reports:

	• Support for the powerpc*-*-*spe* target ports which have been recently unmaintained and untested in GCC has been declared obsolete in GCC 8 as announced here. Unless there is activity to revive them, the next release of GCC will have their sources permanently removed.


Side note: Mixed with clang's powerpc family status for buildworld,
such as ignoring __builtin_eh_return so that thrown C++ exceptions
will not work for the world so built, powerpc*-*-*spe* looks to
have a substantial toolchain problems going forward.
