Well, it's a tough issue, because you'll have to test every change to
see if it really makes a difference or not.
But you might try --disable-float8-byval, --disable-spinlocks. On the
compiler front (CFLAGS), you should have -mtune=54418 (or perhaps
-mtune=cfv4) (-march and -mcpu don't imply -mtune), and even perhaps
-O2 or -O3.
I also see you're specifying -msoft-float. So that's probably your
problem, any floating point arithmetic you're doing is killing you.
But without access to the software in order to change the data types,
you're out of luck in that department.
