I am also Termux user. We use Emacs in terminal. I do not know if it
is compiled for graphics, and is maybe not feasible compiling oneself,
but some people will do that.

Reference: https://termux.com/

One of my mobile devices runs Android and I use Emacs within Termux
when I am on the go. On other devices there is Lineage OS installed, I
use Emacs on Motorola E and E LTE versions to send emails and do
common Emacs stuff like writing. Often I access devices by using SSH.

Then majority of Virtual Private Server instances do not use X, they
need just terminal version. On Debian GNU/Linux runned VPS-es I will
install often `emacs-nox' package version without X, but too often I
need development version, in that case I am compiling it myself with
`./configure --without-all' but somebody could choose `no' to the
toolkit as well.

I guess that there are many ways why X may not be requires on
Raspberry Pi devices.

Without X, I believe that ./configure alone will work and will not
compile X anyway. But why compile X on those operating systems where
there are no X libraries by default, like VPS-es, small computers,
Android and Replicant and Lineage OS systems, no need for it.
