Why is this needed? I don't think Sage should ever use `file`.

Why do we need this? `patch` comes with Sage.

Why do we need this? `lapack` comes with Sage.

Why do we need this? `iconv` comes with Sage.

I don't think these are required anymore.
> * `libgc-devel`
Is this `boehm_gc`? This comes with Sage.
> * `zlib-devel`
Why do we need this? `zlib` comes with Sage.
> * `libncurses-devel`
Are you sure this is needed? Does #12725 help with not requiring
`ncurses`?
> * `make`, `perl`, `m4`
This is already checked I believe.

match
So, the GCC spkg doesn't build on Cygwin? Then also `spkg/install` should
be changed not to install GCC on Cygwin. The version checking already
exists.
> I assume that it should happen in `prereq-1.x-install` and not the
configure.
Please don't! Ideally, `prereq-1.x-install` should be essentially empty
and all checks are done in `configure`. That's how things are supposed to
be done autotools-style.
