portupgrade MAKE_ARGS inheritance bug

[Andrew Pantyukhin]

If MAKE_ARGS is set for a port and you try to portinstall
it for example, then the same MAKE_ARGS are used
for the ports installed as dependencies.

In my case I have this in my pkgtools.conf:
MAKE_ARGS = {
    'mldonkey*' => [
      'CONFIGURE_ARGS="--disable-gnutella"',
    ],
  }

When I tried to install mldonkey, portupgrade tried to
install ocaml with the same CONFIGURE_ARGS. It
failed. I had to install it separately.

Thanks!
