Use the stable, slow moving lang/gcc instead of lang/gcc46 for
USE_GCC=4.6 and USE_GCC=4.6+ and generally whenever the default
version of GCC is employed.

This will significantly benefit tinderboxes and the larger, reasonably
conservative user base by reducing the amount of rebuilds.

Rename _GCC_BUILD_DEPENDS to _GCC_PORT, but still set _GCC_BUILD_DEPENDS
in the end for the sake of some ports relying on that.
