yes
with GCC still defaulting to 15. You assume that the GCC version
matches the version that you are building with.
Also I find the name for the target_version macro a bit confusing,
because it means both, the version for the target, and the version for
the build (the build still succeeds building with 15).
patch attached.
* Fix build with mismatching GCC default version.
