Thanks for that.  I think I've bumped into xf86sym.c previously when
tracking down a problem.  Unfortunately, it's not immediately obvious
(to me) how to include a reference to '.mcount' in C code.  I could
have studied the gcc documentation but Eric came up with an alternative:

This almost worked.  It resulted in an unresolved 'ELO2300' which I
fixed by removing elo2300 from XInputDrivers (I don't need it and
this was quicker than working out why the reference was generated).

Thanks to both of you - profiling now works.  I've located the cause
of the poor performance, all that's left is working out how to fix it.
