I had naively assumed gcc would try to append bin/.  Ok, here's what
is probably my last try on all this unlibsubdir mess, at least for the
next two weeks.  For some reason, I had missed CXX_FOR_TARGET in the
last patch; I fix is included here.  I have also merged the includedir
patches in; I just can't maintain two separate sets of patches for the
same Makefile :-(

Ok to install this one?

I'm not sure I understand what this would do, and I'm so sleepy that
I'd rather not try to understand it now.  Feel free to go ahead and
fix it if you know what should be done.
