Andrew Bird 4c58d4c7e2 CI: Add DOS builds 
1/ Watcom 1.9
   a) Kernel and other directories building fine
   b) Share doesn't support Watcom for TSR.

2/ Turbo C 2.01
   a) Kernel build needs some functions that are missing.
   b) Sys not building for the same reason,
   c) Share building nicely.
   d) Need to figure out how to get tc201 compiler to Github Actions

3/ IA16-GCC
   a) not currently supported by build.bat so commented out

E. C. Masloch 2aa51a1992 boot: move cluster list to 1FE0h:2200h (128 KiB file, up to /L 0x200) 
1FE0h:2200h happens to be linear 22000h. Like the memory map
update to the FAT32 loaders for #127 this allows to load a
file of up to 128 KiB (rounded to cluster size) with an /L
parameter for SYS of up to 0x200.

handle wmake and gmake differences 
wmake requires changing into directory as ignores -C option, gmake ignores cd into directory so requires -C subdir option

Bocke 9b6a8579d1 Make build work on DOS 
Double ampersands are not supported by DOS command line interpreters. The previous would work only on (modern-ish) Windows.

E. C. Masloch 3415ad93c9 boot32: fix very old bug, init high byte of fat_secshift 
It turned out that this loader was severely broken for many years,
at least since 2012 (the git repo's creation). This variable was
read as a word to set cx for a loop, but only the low byte had
been written. The high byte happened to be 0EEh so cn_loop would
always zero out the FAT sector to read.

This _happened_ to work if the first root directory cluster and
all the kernel file clusters were all referenced in the first
sector of the FAT. Otherwise it would blow up.
