Disable threads again; it has caused the more troubles. This time, it has
${PTHREAD_CFLAGS} and ${PTHREAD_LIBS} include in the build to kill the
headache of old '_r' and can't run with something like ruby-opengl, ruby-sdl,
ruby-gtk2 and etc on FreeBSD 4.x or older 5.x. With this commit should solve
those issues. It is recommend you to rebuild any apps that depend on
lang/ruby18, so see the UPDATING for detail.
Remove the 'BROKEN' on the other ports that knu has added them few weeks ago.
Some of them have been tested, so if one of them is still broke then please
let us know and one of us will re-add the 'BROKEN'.
This changes was worked by lofi and me. lofi did everything on FreeBSD 4.x
and I did others. lofi, thanks for help!
