   There is some issues about whether WINTOOL must be set for MSYS2 as well as WINTOOL.
   1. **Symlinks**:  If CYWGIN is used, symbolic links are used unless WINTOOL is defined
then directories are copied.  That is because Windows native tools cannot follow Cygwin's
symbol links.  MSYS2, on the other hand, doesn't support symobolic links.  The 'ln' command
works under MSYS2 but always does a directory copy.  So WINTOOL is not needed for these "fake"
symbolic links with MSYS2.
   2. **Path  Conversions**:  Both CYGWIN and MSYS2 support the `cygpath `program.  All toolchain
paths must be converted to Windows paths using `cygpath `for for both CYGWIN and MSYS2.  But
WINTOOL was never set for MSYS2.  I don't know how that worked???  I did have to do a fix
for this in `boards/` recently with regard to the ZDS-II toolchain which always wants
Windows paths for either CGYWIN or MSYS2.
   I don't understand how MSYS2 with a native toolchain works.  I had no problems with the
MSYS ZDS-II build other with `boards/`.
   I suppose I should do some experimentation because I have both on all of my Windows machines.
