Now that you've moved to CVS libtool anyway: shouldn't you be able to
remove the --tag=F77 cruft, and use LT_LANG(Fortran) and
  configure FC=xlf90

and everything should work fine?
(Except for the FCFLAGS_$SRCEXT which you'll still have to cater for).

Surely LTFCLINK should contain --tag=FC, too.  This needs to be fixed in
Automake.
