OK, it turns out that crtstuff was being built without -fPIC. The reason 
is that other targets define CRTSTUFF_T_CFLAGS_S to include "-fPIC", but 
in t-ppccomm we have:

# There is no need to add -fPIC here because crtstuff is multilibbed
# and so automatically gets -fPIC when needed.
CRTSTUFF_T_CFLAGS_S = -msdata=none

... but I disabled multilib.

FWIW, I understand the need to mulitlib libgcc on ppc-linux, but it 
sucks that libstdc++ and libgcj get multilibbed by default also. The 
builds take forever and waste disk space. I'd like to turn that off by 
default if possible.

And why not have -fPIC in CRTSTUFF_T_CFLAGS_S? It won't hurt if -fPIC is 
specified twice.
