librtemscpu.a has all the POSIX and Classic API support (and a lot 
more).  There is no separate libpthread with RTEMS.

libc.a iSoLikeCandy at yahoo.coms provided with the tools and is newlib.  I 
don't know why they are looking for libc_r.  I guess some hosts put 
their pthread code in that library.

Look at how the rtems-addon-packages are configured and built.  They
override the variables for the compiler and flags to match what you
should be using.  Eric Norum has managed to build a fair number of
packages this way.
