71a7d0d264 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.

7bf4b77233 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).

fbdbc4c25c 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.

33d707ba7f Fix compilation with MSVC 1.52c. 
Needs one more file from the c library, BSS_INIT all uninitialized
globals in config.c and a define of SEEK_SET.

44cf0a17a1 fix and enable i386 support 
This gives ~5K size reduction with bc3.1.
Today no one uses pre-i386 CPUs so there is no good
reason against having an extra optimization.

8187fd8153 disk: fix sectors count truncation for CHS [fixes #10] 
LBA_to_CHS() uses geometry taken from BIOS, but LBA_Transfer()
was using the geometry from VBR. This caused "count" variable
to underflow over unsigned long, then corrupting the entire
DOS memory with the large read.

This patch makes LBA_to_CHS() to return the geometry to caller,
so that the calculus do always match.

Thanks to @ecm-pushbx and @andrewbird for helping to
nail this down.

f4c9691ef5 fix watcom check 
WATCOM var may be defined in autoexec.bat, but this doesn't
mean the user wants to build with watcom.
Check the COMPILER="WATCOM" instead.
