Remove the universal accessor from BuildOptions

BuildOptions is now immutable (finally).
Simplify cxxstdlib_check implementation

The cxxstdlib_check method currently only supports one value, so we can
just define the accompanying instance method when necessary. If we ever
add more options we can back it with a data structure.
nordugric-arc 4.2.0

Release 4.2.0. Patch is no longer needed.
nordugrid-arc: add 4.2.0 bottle.
