[Buildroot] [git commit branch/2018.02.x] skeleton: PAGER without blank and unset at end of for loop

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=8c751db3610f33449cf6ff5bb1826a22e95aef81
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2018.02.x

The PAGER environment variable is including a blank character at the
end. Remove this.
A for loop has been unsetting the variable inside the loop, this is only
needed once at the end of the loop.
