The issue is pretty simple: whether to EMACS to "t", or change it.
IIUC, the original complaint is that Makefile.in in some projects use
the EMACS variable to refer to the emacs executable, and setting the
EMACS envvar to "t" confuses such build scripts.  On the other hand,
changing the EMACS envvar to something else confuses projects that
expect "t".

It's clearly one or the other.  Personally, I think we should revert
the changes, and get whichever projects use EMACS in their build
scripts to use some other variable name instead.
