Currently check_assertion.h checks an assertion by forking and checking the exit code of the child process, but this means such tests don't work on targets where fork doesn't exist (e.g. bare metal targets).
Instead call setjmp just before we call the function we want to test, then longjmp out of __libcpp_assertion_handler with a return value indicating whether the assert happened as expected.
