Solaris uses a -lposix4 and it seems weird that it implies -pthread. 
So, it is not affected.

Don't know about FreeBSD, but it has GNU ld doesn't it?

If other systems need -lrt, and -lrt implies -pthread on those systems 
too, the course of action will need to be evaluated case-by-case.			

I don't know if long term it is possible for Linux to provide a 
libposix4 library that includes librt functionality not requiring 
threads; or to move that functionality to libc.
