clang; gmake

[side light]

   Correction on my last post. Removing "gmake" alone from many Makefiles
   improves many builds, by reducing gmake dependencies and options. This
   is since FreeBSD has its native clang. GNU and GTK tools didn't
   necessarily have to be removed for compile improvements to be made.
   Also, it would be better if ports that use hardware to have an option
   of only DEVD or HAL. I propose to take this into account in port-trees.
   It will in fact make port maintainer's jobs' easier. Thank you.
