Allow overriding CC, AR, and RANLIB from the environment

Rather than unconditionally setting CC, AR, and RANLIB, allow the
environment to override them. This is useful in more circumstances than just
cross-compiling.

Thanks to Tormod Volden <debian.tormod@gmail.com> for bringing this to my
notice though his original suggestion was different.
