'mk_add_options' or 'export' MOZILLA_OFFICIAL
In #27472 (moved), we added
export MOZILLA_OFFICIAL=1 in
.mozconfig-android because we found the compiled APK wasn't releasable (it was still debuggable). This was due to MOZILLA_OFFICIAL not being set correctly at build-time. After exporting MOZILLA_OFFICIAL, the resulting APK is for release. Do we need both
export or do we only need
export? Should we use
export on the desktop builds, too?
