It depends whether debugging is added or not. release and pre-release
are built with `make install-strip`, snapshots are built with `make
install`. Emacs-26 was built with `make install` regardless, and also
was a dumped binary so contained all the stuff now in the pdump file.

The result of all of this is that the executable installer for Emacs-27
is now less than half the size of "no-deps" download for Emacs-26. Of
course, this doesn't impact on space on disk. For release version of
Emacs-27, the difference between a hard linked or duplicated emacs.exe
is 6Mb.
