global: Corrected absolute paths in bin/ symbolic links

# This script produces a h316rc file which has to be sourced by
# the user's shell.
#
# Usage: Just run and answer the questions. Then use
#        the h316rc file by typing ". h316rc". You
#        can also include that into your .bashrc etc.
#        All paths in the file will be absolut.

***************************************************************

Now the necessary environment for the H316 build system
has been set up. 

You have one possibility:
a) Source the h316rc file into your current shell!

Then you can run
               "make" or "make all"
to build all the stuff inside. When make successfully finishes,
you are ready to go.

Have a lot of fun and good luck!
(You should have installed GNU make, GCC, bash and friends!)
