Support Tachyum's processor in config.guess and config.sub

[Jeff Law]

This is a minor patch to config.guess and config.sub to allow them to 
properly identify the Tachyum processor.

config.guess will report "tachy-unknown-linux-gnu" on our standard glibc 
linux configuration.  It presumably would work for musl, but I didn't 
test that as I didn't have a handy musl configuration to test within 
qemu.  There will likely be a day when we support *BSD, but that's 
future work.


config.sub recognizes both "tachy" and "tachyum".  We use both forms.

Thanks,
Jeff
