For newlib targets and a unified tree build,, you could peek at the headers; but in general, this is indeed not solvable in a clean autoconf manner.

Oh, I filed PR 22294 for this bug.

Thanks.

For the avoidance of doubt, we can fix this bug, but autoconf doesn't appear to be the right tool for this. Instead, we can put the information into the target configuration files. FWIW, if we only had to support unified tree builds, we could create a separate configuration step for libgcov after building the target libraries. But that seems more trouble than it is worth.
