Selects HAVE_C_RECORDMCOUNT to use the C version of the recordmcount

This should improve build time. It also seems like the old Perl Version
misses some calls to _mcount that the C version finds.
That would make this a bug fix possibly for stable even.
Any more details on what the difference is, is it just some random
subset of functions or some pattern?
I have not been able to identify any pattern. Will add a few details in
the 'issue' on github.
