Break simple tests into two pieces and see that they work when linked

If an alternate compiler is specified
then the two main

26 # alternate compiler must be installed
, and is specified by defining
27 # ALT_CC_UNDER_TEST in the environment.

on host
, run there and the

then compiled
on build and executed
on target.
