I've thought hard about this and the solution that satisfied me most was
that

    test $srcdir -ef . || test `cd $srcdir && /bin/pwd` = `/bin/pwd`

(properly quoted etc.) means srcdir == builddir.  That means on Solaris
you will invoke the second part, as you suggested in your patch, whereas
if test -ef works you'll get the safer alternative.

I've also installed your prep_buildtree patch to be on the safe side.

One of my concerns is that prep_buildtree isn't super-portable by design
(using 'find'), but we'll just have to cross our fingers that nobody
exercises all these unlikely cases.
