[Buildroot] [git commit] package/zmqpp: don't override variable

[Arnout Vandecappelle (Essensium/Mind)]

commit: https://git.buildroot.net/buildroot/commit/?id=3934a287567661bd56fe067ae258d4a3eab8a3e7
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Instead of reseting the variable when we can't set it, just set it when
we can: we just have to negate the condition.
