libexec/ld.so/powerpc/Makefile.inc needs updating to match, no?

CFLAGS += -fpic -msoft-float

Also, does clang support secure-plt for small pie? If not, then
lib/csu/Makefile needs updating too:
---
# Override powerpc default of -fPIE
# XXX if this is safe, why not override CFLAGS for alpha and sparc64 too?
# Does it work because the csu bits come first and get the first few GOT
# entries?
.if ${MACHINE_ARCH} == "powerpc"
CFLAGS+= -fpie
.endif
