 Same remark about avoiding 6/8 (the reasoning is: if later on patches 7
and 8 disappear and patch 9 is added, it looks strange to have the /8 there).

 bindings is typically used in plural. And actually, most packages will
call it --enable-python or --with-python.

 We normally put an explicit --enable-python-binding(s) here.

 Also, we don't normally indent inside conditions in .mk files
(indentation is reserved for commands and for continuation lines of
assignments).
