    autogen: Allow running autogen from a builddir != srcdir
    
    While the configure correctly supports being run outside of
    the top source directory by default, it's nice if autogen.sh
    does too:
    
     $ git clone git://anongit.freedesktop.org/systemd/systemd
     $ cd systemd
     $ mkdir $(uname -m)
     $ cd $(uname -m)
     $ ../autogen.sh a
     $ make
