it is being done in all tests.  which ones do you think i skipped ?

the sim ports use a unique subdir for their `run` program.  the tests
need to find that path.  this $arch value is what binds the specific
subdir to the test.

as we do multibuilds, we'll have multiple ports active, so a single
variable won't cut it.  moving it here and out of autotols enables
that.  as we do multitarget, this will help smooth the transition as
we won't have to juggle each arch as it migrates.
