On case-sensitive systems, the country code needs to be capitalized for
the language to be correctly identified between two dialects. Since
`br` was not capitalized, we fell back on european portuguese for Linux
and MacOS

Languages that have been abandoned or are not yet sufficiently
translated are not shipped with release. The po files and existing
translations remain and will be re-enabled post release for future
development
Prior to release, we will disable languages that don't meet our criteria
(minimum translation > 75%) but we want to keep the languages available
for translation. LINGUAS lists all languages available.
LINGUAS_INSTALL lists just the languages that will be installed for use
in KiCad. Right now they are the same content. This will be changed
prior to v6 release
