Both build-aux/config.guess and exec/config.guess return
  armv7l-unknown-linux-gnueabi
but I configure all packages with
  --host=armv7l-linux-androideabi
so that all tests of "$host_os" see that it's Android and not an
arm system with glibc.

I took the Emacs sources from git, generated the 'configure' file, and
am compiling it like I compile on other POSIX-like systems. The Emacs
specific configure options that I use are --without-all --without-x.
