Just as important as x86_64 or linux-gnu :-).

Currently when I press C-h C-a, I get this info (amongst other):

GNU Emacs 28.0.50 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.23, cairo version 1.17.3)
 of 2020-09-07

I think it would be handy if there was a bit more info on that page.
I would prefer x64-native GNU/Linux. Why is it less important to know
about non-gui features? For me who has turned off most of gui stuff, GTK
and Cairo versions are not really what I care about. I have them just to
get better font rendering, but now I can maybe compile without at least
Gtk? I mean I don't need to know that it is compiled for GNU/Linux; I
know I am running on a GNU/Linux OS, or that it is a 64-bit OS, yet info
is there.

In my case I would have seen that I didn't compile with native compiler
support even though I intended (since the configure script failed wihout
me noticing).

I also wouldn't mind more info about compiler switches used to build the
version as well as features/packages built-in. I don't know what is
essential more and I don't have any philosophical argument, more than it
is sometimes useful.
