Replying to [comment:3 leif]:
> Shouldn't that currently only be done if we really (decide to) build the
GCC spkg, i.e., in `spkg/install` (rather than `sage-env`)?
Or in `sage-env` but depending on `SAGE_BUILD_TOOLCHAIN`.
> (Sage currently wouldn't fully build with Clang [3.x].)
It doesn't build with Apple's GCC either... but you might have a point, in
case somebody decides to install a custom GCC outside of Sage.
> Also, are all possible versions of XCode's Clang capable of building
GCC?
I'm not sure. But at least one person reported being able to build GCC
with Apple's Clang but not with Apple's GCC.
