GNUSTEP_HOST_CPU would give 'ix86' ; I think if environment variables are
to be used, GNUSTEP_HOST_OS (which would give 'linux-gnu') would be a
better choice.

But likely it would be better to get the information from a /proc
filesystem (if avaialable), or failing that, from uname, and failing that
from some other os function/method/program, and only when all else is
failing I would use shell env variables.

I'm not sure how much information the operationSystemName should return,
or in which format - I would return something like 'Linux', 'Windows',
'Solaris' but I've not read the doc nor compared with what other systems
return.
