#     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.
#     
#     mpe: The perl version misses symbols with '.' in the name for example
#     "lmb_is_removable.isra.3.part.4", and also weak symbols.
