#     powerpc/ftrace: Enable C Version of recordmcount
#     
#     Selects HAVE_C_RECORDMCOUNT to use the C version of the recordmcount
#     intead of the old Perl Version of recordmcount.
#     
#     This should improve build time. It also seems like the old Perl Version
#     misses some calls to _mcount that the C version finds.
