OK I got it now, everything should work fine then. 

Right now there is no policy if the ports tree should try to build everything
threaded. Some ports (at least my ports, when possible) have a USE_THREADS
option which I guess should be default at a future time.

FWIW, the cad/tochnog port gave me less than 5% performance hit when build with
libc_r wrt the non-threaded version (on an UP system - I was just curious).

best regards,

   Pedro.
