Remove (sysv)
...
Replace its usages with direct RAM+ offsets. The (sysv) mechanism was
incompatible with cross-compilation of a full interpreter.

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).

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.
