You should link against libpthread_rt.a, but with a bunch of --wrap
options. xeno-config provide an automated way of getting these options:
xeno-config --posix-cflags give the flags to be used when compiling,
xeno-config --posix-ldflags give the flags to be used when linking.
For an example of Makefile using xeno-config, see
ksrc/skins/posix/demos/Makefile
