Functions which start with rt_ are part of the native skin. The
implementation of the posix skin does not change libc.a, it implements a
new library libpthread_rt.so, and the function substitution is done at
link-edition time by using the linker --wrap option.

You can start here:

For instance the --wrap trick is explained here:
