>Description:
Currently libvpx does not build for sparc64

When running a build from the port directory it currently bins out with;
"no support for sparc64 the moment. testing/patches are welcome"

After a bit of googling I noticed that Debian has a sparc compiled tarball and I just copied their configure line with respect to --target=generic-gnu

I found that base gcc was too old to compile it the configure script was complaining that it couldn't link files.... So I forced the make file to use gcc48 for sparc64 builds. 
>How-To-Repeat:
Build port on a sparc64 machine.
