This still needs to be fixed.

Yeah, for -m32 it is in
.../lib/gcc/x86_64-pc-linux-gnu/9.0.0/32/include/
which isn't that useful; while the finclude/ in there is needed, because
those are target specific, this header is the same and so it could be
just in .../9.0.0/include/ always (like e.g. the std*.h headers, intrinsics
etc.).
