When I was doing embedded work in the past, I usually did a port of newlib so
that the standard header files, abort, printf, existed. There are various
switches you can set to reduce which tests get run. I would look for another
16-bit bit embedded system, and set things up the same way. Look at
doc/sourcebuild.texi and the target-support.exp file in testsuite/lib.
