RFC Additional flags in g77 testsuite

[Billinghurst, David (CRTS)]

After the recent discussion on gcc-patches on additional flags for the gcc
testsuite http://gcc.gnu.org/ml/gcc-patches/2000-06/msg00864.html I tried
the same for g77.

In g77.f-torture/compile you can add compiler flags with a *.x file like

lappend options "-ffast-math"
return 0

To do the same in g77.f-torture/execute we will need to patch
gcc/testsuite/lib/f-torture.exp to make it similar to c-torture.exp, so we
can use a *.x file like

set additional_flags "-ffast-math"
return 0

Before I submit a patch, any comments on the variable name to use.
Exixsting practice isn't consistent.  In c-torture/compile and
f-torture/compile you modify "options", but in c-torture/execute you modify
additional_flags as options is already used.
