Convert to USES=compiler:c++11-lang and remove the now-obsolete GCC option.

This also means that on systems where /usr/bin/cc is clang 3.3 or higher,
there is no option to compile this port with GCC (since it is new enough
for C++11).  On older systems FAVORITE_COMPILER=gcc can be set.

While here use a few more option helpers.
