According to mk.conf(5), COPTS contains "Extra options for the C compiler."
(not restricted to optimization). For pkgsrc, there is the CFLAGS variable
which, according to packages(7) contains "Any CFLAGS you wish passed to
the configure script and/or submake in build stage." I am not sure if setting
this variable should be restricted to the package Makefiles.
