build problems with latest Makefile.in/configure

[Christopher Faylor]

After a successful configure, in a sandbox where I've been building things
from the top level for years, I'm getting errors that are due to the fact
that 'srcdir = .' in the generated Makefile even though my srcdir is located
elsewhere.

I think that there is still some brokenness from the recent top-level
Makefile changes.  I have found that if I copy the Makefile.in from the
gcc repository, everything seems to work fine.

I can't be the only person noticing this, can I?
