Hmmm ... you really shouldn't be using the out-of-line tas.s code for
gcc-based builds on any common architecture. I think the problem may be
that the case statement in src/template/solaris is testing for "i?86"
which probably doesn't match your x86_64 host. What value does $host
have for you exactly?

7.4 is not exactly a spring chicken. I suggest that you experiment with
CVS tip (8.1beta) and document what still needs to be fixed. After we
figure that out, we can discuss whether the changes are reasonable to
back-patch to the 7.4 branch --- but starting a portability
investigation with an old branch is a waste of everybody's time.
