I completely forgot to explain how this was tested.
Bootstrapped and tested on powerpc64-linux, no regressions, with
-m64,-m32,-m32/-mpowerpc64,-m64/-mlra. Also built cross-compilers
and built the Linux kernel for all archs where that works (28 builds).
Over the weekend, I bootstrapped on x86_64-linux, no configure flags
at all. It regchecked fine after a few tries (one fortran testcase
ping-pongs, actual_array_substr_2.f90). Also had to filter out all
ASAN noise of course. And one of the gomp testcases runs for at
least two hours ("./tpow_z", if that means something to anyone).
