USE_GCC=X.Y+ should prefer the stock compiler

    USE_GCC=3.2+ on a 6-CURRENT system prefers the GCC 3.2 compiler
    instead of the GCC 3.4 default system compiler.
    One often uses USE_GCC=3.2+ to enable a port to build on RELENG_4,
    but that does not mean a 6-CURRENT user doesn't want to use the
    native compiler.
    I also argue that the correct algorithm for USE_GCC=3.2+ is:
    1. Use system compiler if it's version is allowable by the USE_GCC
       invocation.
    2. Prefer the highest version # found already installed and allowed
       by the USE_GCC invocation, rather than the lowest.
    3. Install the specified GCC version and use if, if no other already
       installed compiler meets the USE_GCC invocation.

#1 and #3 are implemented with this patch, but #2 isn't.

The reason for it is because there is no highest version # specifiable
with the USE_GCC command. What could be made is that the USE_GCC
command accepts two arguments, where the first is the lower version,
the second is the upper version. Or USE_GCC=-4.0, where everything
<= 4.0 is allowed.
