GCC build: Remove duplicate argument [#fixes #27 ]
...
No need to specify output file in NASMFLAGS as Watcom needs it specified
in the rule. Newer versions of NASM see duplicate output file as an error.

For GCC builds use GNU make instead of wmake throughout.
...
This eliminates all build-dependencies on Open Watcom.

Create init varieties for unsigned long helper functions.
...
An INITPATCH is used to make sure the correct symbols are used.
The GCC kernel now shows the copyright string and boots a little further.

ia16-elf-gcc: provide GNU LD linker script and symbols to link kernel.
...
The resulting kernel and sys.com do not work yet (kernel prints 123 only).
Some functions in sys.com are placeholders.

ia16-elf-gcc port: compile all asm files with -f elf.
...
Because ia16-elf-gcc and the GNU linker do not understand OMF we
need to use ELF everywhere.
This also means we cannot use "wrt", "seg" and "call/jmp far".
Most wrt's are superfluous, and seg and call/jmp far can be
replaced by explicit ?GROUP references (to be defined in the
linker script).

C source code changes so the kernel can compile with ia16-elf-gcc.
...
Use "make all COMPILER=gcc".
Linking does not work yet with these changes.
