x86_64 is used as a baseline: the "x86_64" entry, whatever status it has,
is transformed into "all", and then the other entries in ARCHITECTURES
either dropped or rearranged appropriately.
* optipngtranslator: add 2ndary arch
* The package was not installable, because it needed
cmd:optipng_x86 on 32bit Haiku. I removed the check of
$buildArchitecture and "targetArchitecture and always
use the plain cmd:optipng.
optipng is available for all architectures.
* Add 2ndary architecture so _x86 apps can use the
_x86 version of the translator.
* Improved description
* Bumped revision
* Referring the current haiku version explicitly is not needed, since
the RequiresUpdater takes care of setting the version of Haiku used
for building a package.
