Commit Message

Philippe Mathieu-Daudé Nov. 5, 2020, 5:15 p.m. UTC 
Add rules to select some crossbuild jobs.

The following tags are available to restrict the CI jobs:
- all    (select all jobs, this is default)
- cross  (select all cross-jobs)
- system (select all cross-system jobs)
- user   (select all cross-user jobs)
- $ARCH  (select an architecture: arm/mips/ppc/sparc/...)

Developers can combine tags in the QEMU_BUILD variable when
pushing a branch (or tag) to repositories. Examples:

  $ git push -o ci.variable="QEMU_BUILD=user"        myrepo mybranch
  $ git push -o ci.variable="QEMU_BUILD=user,system" myrepo mybranch
