Android/Termux: How to build gpg-agent without maintainer mode?

[Felix E. Klee]

I managed to get `gpg-agent` run with USB smart card support under
Android/Termux:

What bugs me is that I had to compile in maintainer mode: Now I get
warnings that the software should not used be used with production keys.

Maintainer mode is in fact suggested by `autogen.sh`:

    $ git clone git://git.gnupg.org/gnupg.git
    […]
    $ cd gnupg
    $ export C_INCLUDE_PATH=$PREFIX/include/:$PREFIX/include/libusb-1.0/
    :$PREFIX/include/libandroid-support
    $ ./autogen.sh
    […]
    autogen.sh: You may now run:
      ./configure --sysconfdir=/etc --enable-maintainer-mode  && make

If I try without maintainer mode, then I get:

    $ ./configure
    [output attached]
    $ make
    make  all-recursive
    make[1]: Entering directory '/data/data/com.termux/files/home/src/g/
    gnupg'
    Making all in m4
    make[2]: Entering directory '/data/data/com.termux/files/home/src/g/
    gnupg/m4'
    make[2]: Nothing to be done for 'all'.
    make[2]: Leaving directory '/data/data/com.termux/files/home/src/g/
    gnupg/m4'
    Making all in common
    make[2]: Entering directory '/data/data/com.termux/files/home/src/g/
    gnupg/common'
    make[2]: *** No rule to make target 'audit-events.h', needed by 'all
    '.  Stop.
    make[2]: Leaving directory '/data/data/com.termux/files/home/src/g/g
    nupg/common'
    make[1]: *** [Makefile:613: all-recursive] Error 1
    make[1]: Leaving directory '/data/data/com.termux/files/home/src/g/g
    nupg'
    make: *** [Makefile:533: all] Error 2

*How do I build `gpg-agent` without maintainer mode?*

Note that I only need the agent, so I could probably speed up compile
time by quite a lot if disable the other tools in `./configure`. But
that’s not a priority now.
