defunct fortran built by default for cross-compiler

I've found that the problem was related to configure deciding to build
fortran and enable runtime tests for it when doing check-gcc even though
libgfortran was not present; I had made my script remove that some time
ago because libgfortran was not supported.

When I tried to configure with libgfortran present and add the make
target all-target-libgfortran, I get after about three hours:

So, it appears the only way to do a regression test now is to hard code 
with --enable-languages the set of languages that are known to generally 
work, I.e. c,c++ and objc.
