gcc: remove g77/f77

g77/f77 has been removed from gcc 4.0.0 via commit:

* b4117c30610 Makefile.def, [...]: Remove all mention of libf2c.

When set

    FORTRAN = ",f77"

it complains with error:

| The following requested languages could not be built: f77
| Supported languages are: c,c,c++,fortran,go,lto,m2,objc,obj-c++

So remove g77/f77 from gcc recipes.
