The threads libraries don't have any strong symbols that
don't begin with an underscore:

  $ nm /usr/obj/.../lib/libc_r/libc_r.so.5 | grep " T "

If libc also doesn't have any strong symbols (at least for
the functions you want to check), then I suppose you can
check the linked application for these (strong) definitions.
I don't know how to do it myself, but this may give you some
idea.
