Subject: GCC build rule doesn't depend on Binutils

In an attempt to test the GCC build rule (without Binutils, because its too
architecture dependent), all the necessary dependencies were moved to GCC
(from `ld'). Also `fortran' was also added to the languages supported by
GCC. This rule built GCC 8.2.0 nicely on my GNU/Linux system. But `gcc' is
still not a final target to built, so the rule is being ignored for now.
