GCC never outputs '.file 0', which is why
this test is only needed for Clang, correct?

No, GCC outputs .file 0 if it during configure time detected assembler that
supports it and doesn't have any of the known bugs related to it.
But that means kernel doesn't need to care because GCC already took care of
that.

OK, then I am fine with the current code.

Thanks for the clarification.
