This has races of its own, since creating INSTALLED is not
an atomic operation.
Could you instead invoke "make install" on just one host,
and "make install-arch-dep" on the remaining platforms?
That should install just one copy of the architecture-independent
files. If this doesn't work now, perhaps we should make it work,
or add another makefile rule that would work.

It may make sense to have a build-time option to not compress,
bit I thought the point of compressing was to improve performance
more than to save disk space, since these days CPU cycles are
often cheap compared to I/O. Have you measured the performance of
Emacs startup with and without compression, if the startup files are
cached and/or not cached?
