In theory, yes. Anyone can hook up a mainboard into the test system. And
anyone else can then submit bios images to be tested to those
distributed machines. Also, the bios images built with every svn commit
are sent to all connected machines, making sure there are no
regressions.
Unfortunately the system is currently unused when I quickly needed that
one bios savior for 39SF020 parts in another project.

Sorry if I sounded bitchy. I don't want to be. Though I think we should
try to follow the rules that all good things are simple.

You can add the following lines to your
target/<vendor>/<board>/Config.lb:

option CC="i386-elf-gcc"
# this one is CFLAGS.
option CPU_OPT="-O2 -Wl,..."
option HOSTCC="gcc"
