Add IPv6 support to dillo

The current Dillo browser (3.2.0-2) packaged in Arch does not browse IPv6 websites. This can be reproduced by trying to browse an IPv6-only website, like my own: https://kzimmermann.0x.no

The upstream repository notes that there is IPv6 support in dillo, but it must be explicitly enabled in the configure options to compile it in. Please patch the build script in order to enable this convenient and future-oriented feature in the native Arch package.

Steps to reproduce:

1. Install dillo: pacman -S dillo
2. Open dillo: dillo
3. In URL bar, type https://kzimmermann.0x.no or any another IPv6-only website and press Enter.
4. Dillo is unable to load that website because it cannot locate the address.

Steps to fix:

1. Edit PKGBUILD line 37 to append --enable-ipv6:

./configure --prefix=/usr --sysconfdir=/etc --enable-cookies --enable-tls --enable-ipv6

added priority3-normal severity4-low statusunconfirmed labels

assigned to @freswa, @toolybird, and @gromit

added scopefeature statusconfirmed labels and removed statusunconfirmed label

assigned to @carsme and unassigned @freswa, @toolybird, and @gromit

closed with commit 2df576ce

Thanks for reporting, fixed :)
