If I remember correctly (Ignatios cleared this up a while ago, so I hope
I'm not forgetting), COPTS is for compiler optimisations that should be
used where optimisations are relevant (some things prefer no
optimisations), CFLAGS is for compiler flags that are set for all
compiling, and COPTFLAGS are compiler flags that are used when building
the kernel.

/etc/mk.conf
There is also a sample mk.conf that has tons of options explained:
/usr/pkgsrc/mk/mk.conf.example

I built the entire source tree from scratch with 68060 optimisations, then
did it again to see how much faster it was (the second time around the
68060 optimised compilers and tools were used).

I don't remember the exact numbewrs, but I went from 18 hours for the
whole source tree to 17 hours. Well, it's something!
