Looks like embedded PowerPC is going to die in GCC:

Hi all,

I propose to mark powerpc*-*-*spe* as obsolete in GCC 7.  This includes
the spe.h installed header file, all the __builtin_spe* intrinsics, the
-mfloat-gprs= command-line option, and the support for the SPE ABIs.

No one has properly tested these targets in a long time (the latest
testresults I could find are from July 2015, >1000 failures), and the
SPE support makes a lot of code much more complex.

Any objections to this obsoletion?  GCC 7 will then be the last release
with support for SPE (it will need --enable-obsolete to build these
targets), and we will delete the SPE support during GCC 8 development.
