portconf is simply a quick way of adding entries to make.conf without
having to put in explicit conditional statements like:

.if ${.CURDIR:M*/x11-toolkits/qt33}
  WITH_KDE_PATCHES=yes
.endif

What actually works as an entry depends on the ports system and each
individual port makefile. It's primary use is setting portknobs. With
something like MAKE_ENV+=.. you are depending on the port Makefile
not setting MAKE_ENV or setting it with a "+=" rather than "=".
