I thought about that... and decided to do what I did.
It is a bit more difficult to do something very similar to what you propose.
We have different stdenvs for different platforms, and some platforms
have fixed either glibc or another thing. Cross-building, it gets
quite flexible; there is "libcCross", and it points to either a uclibc
or glibc, depending on what the user chose.
I could have done: if (stdenv.cross.libc == "glibc"), and then take
libiconv as a usual input. Do you prefer this way? This would be easy.

Lluís.
