I think that he meant how to *detect* Maemo (i.e, without having to
ask the user).

I used to check for the existence of libosso, but since it's available
in Debian (http://packages.debian.org/libosso) I'm also checking
whether we're running inside the scratchbox, so you could use
something like this:

if $PKG_CONFIG --exists libosso && readlink /etc|grep -q ^/targets; then
   DETECTED_PLATFORM=maemo                                                      
fi

If there's an "official" way (or just a better one) to detect if we're
compiling for Maemo I'd like to know.
