Yep, that did the trick, thanks.
What's going on (though I don't fully understand why) is that make
chokes on the fact that LIB2ADD contains
$(srcdir)/config/rs6000/ibm-ldouble.c twice, once from rs6000/t-ppccomm,
and another time from rs6000/t-ppccomm-ldbl. Since the latter only adds
that single file, removing it in libgcc/config.host should do the trick.
I need to investigate a bit further, though: how/why did I get us there,
and what's the best way out. I see that there's a third fragment which
adds that file (but does a bit more): rs6000/t-ibm-ldouble.
