Yes, but such tests can only verify that the basics work, whereas the
OP seemed to indicate that it generally works, but fails in some
subtle situation. If libgccjit you are testing at configure time only
"mostly" works, you will be unable to detect that with simple tests.
For such subtly broken versions of libgccjit, we have no practical
means but looking at their version.

If that is the case, then there's no problem we need to solve here.
