>Description:

This patch introduces a new knob "USE_GCC_RELEASE". It provides an opportunity
for users who prefer stable release (lang/gcc) rather than snapshots (lang/gcc4*)
to stay with lang/gcc if its version satisfies USE_GCC requirement. It is
useful in tinderbox.

For example, a port with USE_GCC=4.6+ will depend on lang/gcc46 if lang/gcc was
not installed. With USE_GCC_RELEASE=yes, the port will depend on lang/gcc
instead of lang/gcc46. It eases the pain to rebuild snapshot again and again
(weekly/bi-weekly/monthly updates).

Maintainer (gerald at FreeBSD.org) is cc'd.
