(971016): g77 driver change && testsuite problem

[Mumit Khan]

With recent changes to g77 driver (Richard Henderson patch on 10/12), which 
btw doesn't seem to be documented in the ChangeLog files, running check-g77 
fails. Here's an excerpt:

===
Running /homes/src/egcs/gcc/testsuite/g77.f-torture/compile/compile.exp ...
Executing on host: /homes/src/egcs-971016/LINUX/gcc/g77 -B/homes/src/egcs-971016/LINUX/gcc/ --driver=/homes/src/egcs-971016/LINUX/gcc/xgcc /homes/src/egcs/gcc/testsuite/g77.f-torture/compile/toon_1.f  -w  -O0   -c  -o /tmp/toon_1.o   
compiler exited with status 1
output is:
f771: Invalid option `-fdriver=/homes/src/egcs-971016/LINUX/gcc/xgcc'

Seems like a trivial problem to fix, but I'm clueless when it comes to
dejagnu.
