This adds checks for Watcom C DOS cross-compiler in a manner analogous to mingw
compiler for Windows. The compiler is not commonly present in Linux distributions
due to a non-free license.

Now that we have multiple firmware backends it no longer makes sense
to write object files to the same directory as their source. A better
solution is to write the object files to a per-firmware directory
under a top-level object directory.
The top-level object directory can be specified on the command-line
with the O= variable, e.g. make O=/tmp/obj. If no top-level object
directory is specified an 'obj' directory is created in the top-level
of the Syslinux source repository.
All the existing make targets continue to work as before, however now
they apply to all firmware backends, e.g. 'make installer' will build
the BIOS, 32-bit EFI and 64-bit EFI installers and place them under
$(OBJ)/bios, $(OBJ)/efi32 and $(OBJ)/efi64 respectively.
Note unlike every other bit of Syslinux, the gpxe objects are still
kept in the src directory, e.g. gpxe/src, since gpxe is only required
by the BIOS backend.
It is possible to specify a make target for a specific firmware or
list of firmware with the following syntax,
make [firmware[,firmware]] [target[,target]]
To clean the object directory for just the BIOS firmware type,
'make bios clean'
To build both the 32-bit and 64-bit EFI installers type,
'make efi32 efi64 installer'
Since the Syslinux make infrastructure is now more complex a new file
doc/building.txt has been created to explain how to build Syslinux.
The top-level Makefile now exports some make variables for use in
module Makefiles,
- topdir - the top-level source directory of the Syslinux
repository, e.g. /usr/src/syslinux
- objdir - the top-level object directory for the firmware
backend currently being built, e.g. /obj/syslinux/bios
- SRC - the source directory in the Syslinux repository for the
module currently being built,
e.g. /usr/src/syslinux/com32/libupload
- OBJ - the object directory for the module currently being
built, e.g. /obj/syslinux/bios/com32/libupload
Since we're rewriting the Makefile infrastructure anyway it seemed
like a good idea to add parallel support. By writing subdirectories as
prequisites for make targets the objects in those subdirectories can
be built in parallel.

We already require a new enough version of NASM that the -Ox option is
supported, so just use it.

Move the MCONFIG files into a mk/ directory and give them more
descriptive names.
This is purely a cosmetic change to make the 'include' directives a
bit more coherent by making it obvious exactly which MCONFIG file
we're including. For example, in com32/lua/src/Makefile we exchange
the line,
include ../../MCONFIG
for the much more comprehensible,
include $(MAKEDIR)/com32.mk

Move copybs to dosutil, change the Makefile to deal with UPX being
able to compress (e.g. very small files.)

Most systems won't have Watcom installed, so don't remove
Watcom-generated binaries even with "make spotless".

Update mdiskchk and add a Makefile. Note that since this needs
OpenWatcom to compile, we still check in the binary file (which is
quite small, anyway.)
