I agree this is possibly the best way out. Though, we're talking about
the kernel, and it might be slightly harder than usual to get this
accepted. But that's not an excuse to use clear anti-patterns in a
toolchain.

If you're felling adventurous, you might propose on the binutils list
for some UAL-specific macros to be set by both compilers (and there
may be enough closed-source compiler engineers listening), so the
*feature* checking macro will be widespread.
