I've studied what Debian does, and they do conditionals based on the
host.  I could find a way to achieve this with Guix and pushed as commit
f1cf62f5dc.

As discussed in #guix, I've disabled static libraries for now.  I've
also only used the flags which are specific to antlr3c and that need to
be changed from their default values, to keep the noise level as low as
possible.

With this, the base for Linphone is now merged and we can attack the
more interesting bits.

Thanks!
