In my previous build, I had mistakenly forgotten to include the
configure '--host=armv7l-linux-androideabi' option. Thus my build skipped
a couple of of stumbling stones. Sorry about that.
Now, with this option included, I'm getting two other problems in the
first place:
1) Although I have installed ncurses-6.4 and put -I and -L options
so that libncurses should be found, the build fails while linking the
'temacs.tmp' executable:

----------------------------------------------------------------------
The reason is that in src/config.h, the macro TERMINFO is no longer defined.
The cause are these two pieces of configure.ac:
AC_CACHE_CHECK([for library containing tputs], [emacs_cv_tputs_lib],
[if test "${opsys}" = "mingw32" || test "$opsys" = "android"; then
emacs_cv_tputs_lib='none required'
else
# curses precedes termcap because of AIX (Bug#9736#35) and OpenIndiana.
tputs_libraries='tinfo ncurses terminfo curses termcap tinfow ncursesw'
mingw32 | android)
TERMINFO=no
LIBS_TERMCAP=
;;
$opsys is apparently 'android' in the Termux build, derived from $host_os.
I got past this stumbling block by hand-editing the generated configure
file, taking out these two comparisons of $opsys with 'android'.
2) Then it fails later, while loading "version.el":

-------------------------------------------------------------------------------
Looking at version.el, this looks like some
(eq system-type 'android)
test that was meant for the Android GUI, now applying to the Android Termux
build.
3) I'll get to testing the "Error: permission-denied" from function
add-name-to-file only after I'm past the errors 1) and 2), since it comes
from a later point in loadup.el.
