Is -pthread also applied when the binary is built, or has it been 
lost?

If you compile a trivial hello-world type program with '-v -pthread', 
does the output show that an alternate libc or a threads library is 
being used?

Unfortunately, support for -pthread or -pthreads in GCC is 
platform specific since it is intended to emulate what the platform's 
native compiler (if it has one) does.
