68f359d6c2 Add xcomp unit for cross compilation 
Memory mapping is a dead end too, solution has to be at a higher
level. xcomp is my new approach.

Replace bin2c.sh with a more portable implementation. 
`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.

2af959a13d Don't use IMMEDIATE in icore 
Since the fix of its RAM addr, we use the wrong CURRENT in every
usage of IMMEDIATE in icore. We therefore have to manually set the
flag for all 3 immediate words in that unit.
