build: fix djgpp builds

2021-01-28T03:08:57+00:00

- Update build instructions in packages/DOS/README

- Extend 'VPATH' with 'vquic' and 'vssh'.

- Allow 'Makefile.dist' to build both 'lib' and 'src'.

- Allow using the Windows hosted djgpp cross compiler to build for MSDOS
  under Windows.

- 'USE_SSL' -> 'USE_OPENSSL'

- Added a 'link_EXE' macro. Etc, etc.

- Linking 'curl.exe' needs '$(CURLX_CFILES)' too.

- Do not pick-up '../lib/djgpp/*.o' files. Recompile locally.

- Generate a gzipped 'tool_hugehelp.c' if 'USE_ZLIB=1'.

- Remove 'djgpp-clean'

- Adapt to new C-ares directory structure

- Use conditional variable assignments

Clarify the 'conditional variable assignment' in 'common.dj'.
