> cleanup:
>
> * Most notably, translation files included under
> '${prefix}/libexec/mame/language': Currently we include *.mo, as well as
> *.po and *.po~. Whereas only *.mo are needed. However, the extra files do
> not cause any issues with the software. And they are tiny... in the very
> low kilobyte range.
> * Python variants cover versions 3.6 through 3.9. Simplify the port to
> limit variants to the two latest Python releases, 3.8 and 3.9
> * By default, Mame is built with debugging info. Add an explicit 'debug'
> variant to allow toggling on and off.
>
> These issue will be fixed when the Mame project releases 0.227, or sooner
> if said release is delayed beyond December 2020.

New description:

 Presently, the 0.226 port of Mame includes a few things that need cleanup:

 * Most notably, translation files included under
 '${prefix}/libexec/mame/language': Currently we include *.mo, as well as
 *.po and *.po~. Whereas only *.mo are needed. However, the extra files do
 not cause any issues with the software. And they are tiny... in the very
 low kilobyte range.
 * Python variants cover versions 3.6 through 3.9. Simplify the port to
 limit variants to the two latest Python releases, 3.8 and 3.9
 * Add a 'debug' variant.
 * Disable 32-bit build support.

 These issue will be fixed when the Mame project releases 0.227, or sooner
 if said release is delayed beyond December 2020.
