I tested it myself, and it brought the generation time down from ~3
minutes to about 20 seconds, so I've applied the patch.  I don't see any
difference in the results, but then again, if failed with this both
before and after the change:

subprocess.CalledProcessError: Command 'wget -a ../download.log -O ../emacs-src-cache/mingw-w64-libtiff-4.3.0-6.src.tar.gz https://sourceforge.net/projects/msys2/files/REPOS/MINGW/Sources/mingw-w64-libtiff-4.3.0-6.src.tar.gz/download' returned non-zero exit status 8.
