Why isn't the test program in target-supports.exp just a link-time test
that __cxa_atexit exists? In other words:
void main () {
__cxa_atexit (...);
}
Is the idea that we want to be able to run the tests with
-fno-use-cxa-atexit in the command-line options? I guess we have to
worry about that. In that case, yes, I guess an assembly-scan test in
target-supports.exp is the best that we can do.
