Libiconv built as a dependency of Git

Prasenjit Saha reported that while building on a macOS, Git complained
about not finding `libiconv' functions. Therefore with this commit,
`libiconv' is also built as a dependency of Git.

Also, since the build of Binutils (and the subsequent GCC) doesn't depend
on the exact versions of the other basic software, they are set as
existance-only prerequsites (ignoring their timestamps). This is done to
avoid re-building when it is not needed.
