The main reason for this is that xlc_r automagically links in the reentrant c library and has different startup code (it uses crt0_r.o or something like that instead of crt0.o). You can compile threaded programs with xlc, but you have to jump through a few hoops to do it. It's just easier to use xlc_r.
