- Make sure pre-existing (arch-independent) update-alternatives
are wiped before registering new ones.
Since update-alternatives has no reliable way to check if
a certain 'generic name' exists, brute-force it and ignore
any error (boo#1208248).
- Remove totally pointless - ie. never executed - %%posttrans
script.
- Restore generic link for update-alternatives. This is usually
set by the update-alternatives and it is '%ghost'ed but rpmlint
complains.
- Add rpmlintrc rules to avoid false positives from consistently
guessing the update-alternatives generic name wrong.
- Make arch dependent generic names conditional.
