testglue.c (which is used for exit/abort wrappers in the testsuite)
isn't c23 compatible. The testing harness tries to build testglue.c
and use it, but doesn't report a failure if the build fails, instead
it's just not used. As a result we get all kinds of failures on targets
which depend on testglue to report back simulator status -- like tens of
thousands of execution failures.
This patch just adds -std=gnu17 to the command line to build testglue.c.
There's other fallout from the c23 change.. My tester is chewing
through things right now...
Installing on the trunk.
