After working around bug#65319, the build of Emacs in the Termux app
on Android 11 fails like this:
$ make
...
cp -f temacs bootstrap-emacs
rm -f bootstrap-emacs.pdmp
./temacs --batch -l loadup --temacs=pbootstrap \
--bin-dest /usr/local/bin/ --eln-dest /usr/local/lib/emacs/30.0.50/

*** "make all" failed with exit status 2.
The line "fdsan: attempted to close file descriptor 2, expected to be unowned"
is apparently emitted by Android's "file descriptor sanitizer".
There's a discussion of this message here:
https://github.com/termux/termux-packages/issues/6592
and a workaround patch has been posted here:
https://github.com/termux/termux-packages/blob/master/packages/emacs/disable-fdsan.patch
With this workaround patch, the build gets much further: It produces a
working 'src/emacs' executable.
Would it be possible to
- either change Emacs' FILE / dirfd handling so that it no longer produces
this fdsan alert,
- or include the workaround patch in Emacs upstream?
