util/crossgcc: Add option to get packages from coreboot's mirror

coreboot has been keeping a mirror of all the toolchain packages used
for releases for quite a while now.  This adds an option to fetch the
packages from the coreboot mirror directly to buildgcc.

This can help with both our releases and when one of the various
servers experiences interruptions or changes a path.

To do this, the URL and filename needed to be split apart, which led to
quite a few changes in the buildgcc script.
