fixed typo: thanks asmeurer
* add ability to install into a separate clean installdir instead of
    _build PREFIX
    e.g. usage: ./configure --prefix=${INSTALLDIR}
    for python apps:
    $PYTHON setup.py install --prefix=./ --root=${INSTALLDIR} || exit 1
corrected the problem statement as suggested:
  * FIX: make build fallback to the recipe dir even if there is a
    non-recipe path with the same name in the current directory.
    thanks asmeurer
