--driver=xxxx in g77 bug

[H.J. Lu]

While doing make check, I got

Executing on host: /home/work/gnu/bin/egcs/gcc/g77 -B/home/work/gnu/bin/egcs/gcc/ --driver=/home/work/gnu/bin/egcs/gcc/xgcc /home/work/gnu/src/egcs/gcc/testsuite/g77.f-torture/execute/cpp.F  -w -O2    -lm  -o /tmp/cpp.x   
f771: Invalid option `-fdriver=/home/work/gnu/bin/egcs/gcc/xgcc'

gcc driver changes --driver=xx to -fdriver=xx.
