* Update docs/submodules/releng from branch 'master'
  - Merge "Bug fix: generate fuel reporting page when no aarch64 available"
  - Bug fix: generate fuel reporting page when no aarch64 available

    In fuel we may deal with x86 or aarch64 architecture
    We generate dedicated reporting page
    - fuel@x86
    - fuel@aarch64

    However when there is no results for one of the architecture
    the test on the number of architecture lead to a bug
