Please elaborate!
So far, all scripts I have seen are severely broken, and offer no
advantages over
configure, so this seems like a documentation issue to me.

You put your arm binary into /usr/local/lib, really?

Should be --target-os=android

Should not be necessary

This is a debug option, it may be useful to test --enable-speex, you should
not use it for production.
(You may want --disable-all if you need smaller libraries)

These are necessary although surprising, see above.

Copy/paste error, this was -lspeex in my mail.

Please run "file /usr/local/lib/libspeex* and consider doing what the
error message suggests.
