My bad, meson 0.47.1 doesn't understand this indeed, fixed in v8.

Makes sense.

This is the check added in the last revision per Maxime's suggestion.
Disabled the check on Windows in v8 until pmdinfogen supports COFF (and this
will probably introduce an alternative dependency).

I'll watch new CI results, haven't been doing so closely because failures were
expected for these patches. Tested v8 build on Linux->Linux, Linux->Windows,
Windows->Windows (GCC & clang, without pyelftools installed).
