  Log:
  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.
