You should find a way to test that this is TRTTD for all gcc releases still
supported for building a kernel (which may mean finding a 4.8 or 4.9 to
test on to see if it uses relative or full paths).

Removing these functions for kernels built with pre-change gcc will cause some
semantic changes. Probably the *right* thing to do is to figure out what
release it was changed in, and do some hacking to include/config/compiler-gcc.h.

In addition, any such patches should be at least non-hostile to the ongoing
effort to get a kernel tree that builds with clang rather than gcc.
