PATCH: Fix ref15.C on bare-metal targets


The g++.dg/init/ref15.C test depends on being able to return from
"main", and then (via a static destructor) call "_exit" to set the
exit code.  That doesn't work on targets that use the testglue
wrappers; the wrapper prints the exit code upon return from "main" and
before "_exit" is called.

Committed as obvious, with testing on arm-eabi.
