The test you have added is a good addition. I am asking, why not keep both
tests? It comes down to the error message and how user friendly it is. If
'rtems.h' is present we can assume it is an installed RTEMS. The second test can
check the quality of the install. I would like to avoid users needing to dig
into a config log to find an error and then try to understand it to figure out
they have a bad path on the command line.

What is the error report with just the 'main' test you added and an invalid
RTEMS path?
