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.
