abort() does not work correctly
|Reported by:||axeld||Owned by:||axeld|
|Has a Patch:||no||Platform:||All|
Although its implementation doesn't look that wrong, abort() does only exit the current thread, not the team.
I've added a test application under src/tests/system/libroot/posix/abort_test.cpp that reproduces the problem.
I originally noticed this bug as part of the problem described in #4778.
