[svn-r10174] Purpose:
Bug fix

Description:
acsite.m4 contains macros to handle fortran compiler.  Some of these macros
are obsolete with automake 1.9.5, but some of them are still used.
These macros need to refer to the fortran compiler as $FC, not $F9X.

Solution:
The version of acsite.m4 with this change didn't get checked in last time.
Oops.
Replaced all occurances of $F9X with $FC and $FFLAGS with $FCFLAGS in
acsite.m4.

Platforms tested:
copper, modi4 (serial and parallel), kelgia, eirene.
	Some errors from btree code and ph5diff.  No errors in fortran/test.
