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
 * 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.
