Maybe we can separate LinuxBIOS into 2 parts.  The first part contains
the core of LinuxBIOS, and the second part contains different extensions
for different archs and elf loader at the end.  We could have something
like the following in the config which is pretty much like Ron suggested
before

extension1
extension2
extension3
elfloader ide usb net
