I would support having MK_PROFILE default to off for 13.  WITHOUT_PROFILE=yes
is something I've been adding to make.conf (or src.conf) for 2 decades.

The mcount-based stuff does not seem compelling compared to sampling via
hardware counters.  It also requires MD code that doesn't even work on
all platforms (e.g. I think the mcount bits for MIPS only work for o32
and are completely broken for n64).  Do we know if any other systems still
ship -pg libraries as an option?  Also, is anyone still using them?
