Work on the power-ieee128 branch has hit a snag...

[Thomas Koenig via Gcc]

... in

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=103476, a very
strange error where an invalid Makefile is generated with
--enable-maintainer-mode on POWER.

I'm not sure how to proceed from here.  Maybe somebody
with more make debug fu could take a look?

Best regards
