[Buildroot] [git commit branch/2018.02.x] package/dash: don't build in paralle

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=2f2097f111180ad3924cc167179c27a6c38d3ac6
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2018.02.x

dash has races in its Makefile, but upstream is not too keen in fixing
those, and just suggests that dash not be built in parallel:
