As I recall, the problem with --with-vanilla is rpm complains over
-vanilla. I think there are 2 possible fixes, changing the variant from
"-vanilla" to ".vanilla", or just dropping the variant all together.
In
my opinion, I prefer this solution because it cleans up the spec quite a
bit, but I am also not a big user of "--with-vanilla". For people
wishing to have vanilla marked, you can always 'echo vanilla >
localversion", though it wouldn't be automated based on the build args.
