Thanks for the patches, HJ, they tidied powerpc64le too.
With gcc (Ubuntu 6.2.0-5ubuntu12) powerpc64le fails a bunch of gold
tests, and one ld test:
FAIL: Could not link a dynamic executable using local ifunc.
Digging into that fail reveals "text relocations and GNU indirect
functions will result in a segfault at runtime", which is the result
of gcc using crt1.o for default PIE rather than Scrt1.o (which it uses
for explicit -fPIE -pie). So there is a gcc-6.2 bug causing this
problem. I haven't yet investigated whether this bug is already fixed
