Disconnect powerpc from the default tinderbox for now.

The wrong toolchain was set in MAKE_PARAMS_powerpc, however, there are
some other issues preventing powerpc from building in tinderbox:

1) There is no powerpc-gcc and powerpc-xtoolchain-gcc port that
   provides an external 32-bit powerpc GCC toolchain.

2) On other targets, the same toolchain can build all of the
   architectures for a given target.  MIPS achieves this by always
   setting -mabi and -EB/-EL explicitly instead of relying on the
   compiler's default architecture.  PowerPC might be able to do the
   same thing, but as of today, powerpc-gcc would be required for
   powerpc and powerpcspe and powerpc64-gcc would be required for
   powerpc64.  Our existing logic for make universe does not permit
   per-MACHINE_ARCH toolchains.

I tried hacking TARGETS_powerpc to only include powerpc64 when
powerpc64-gcc was present, and while that skipped the 32-bit worlds,
it tried to build all the kernels.
