It's taking everything before the first dash and feeding it into a big if/else
staircase. In theory arrcchh6644 should work, and m68k and x86_64. but "arm" it
doesn't known armv5l vs armv7l (different kernel configs)...

I've never set it on the mkroot command line before, so it's always been a local
and never exported from mkroot into child processes. I can add an explicit
"unexport", or I could rip the suffix plumbing out of make.sh.
