Replace bin2c.sh with a more portable implementation.

Browse Source 
`xxd' is not available on all systems, and on others does not support
the `-i' flag. Since bin2c.sh relied on a tool that I can't seem to find
a compatible version of, I have included a simple, portable replacement in C.

Usage remains the same:
bin2c ARRAYNAME < inputfile > outputfile.

This change is also reflected in emul/Makefile.
