f62376bd0a boot: remove _bend 
It's not needed anymore now that the boot binary is built in one pass.

7aa1be070b emul: build boot binary in one pass 
... instead of building boot.fs, and then z80c.fs/icore.fs in separate
passes. This strengten xcomp by making it support 2 completely separate
dicts (that is, the X dict is *not* connected to the system dict. The chain
now stops at EXIT def in boot.fs).

Memory mapping is a dead end too, solution has to be at a higher
level. xcomp is my new approach.

1c6e979028 link: new unit to relink dictionaries 
Not quite functional yet, but works in toy situations. The goal is to
concatenate RC2014's bootstrapped dict to the boot binary.

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.
