Right, but while working on this I discovered GCC's -mrecord-mcount (and
the kernel using this), so how much do we really still need the
record-mcount tool?

Do we really only need the tool for the little hole between gcc-4.6
(minimal supported GCC version) and gcc-5 (when -mrecord-mcount was
introduced) ?
