[v2] gcc toolset linker options on darwin

When I build my project using the darwin toolset I get the following 
warning:

g++: unrecognized option `-pthread'

when building, and the following error when linking:

ld: can't locate file for: -lrt

I traced the -lrt back to the bottom of the gcc toolset. In the default 
case of that switch statement, it says:

flags gcc OPTIONS <threading>multi : -pthread ;
flags gcc FINDLIBS-SA <threading>multi : rt ;

If I remove those lines, both the warning and the error goes away.

I'm using the latest released version from source forge.
