Get benchmarks working on 9.10

Is your enhancement request related to a problem? Please describe.

We have benchmarks disabled on 9.10. I tried to build them with this:

  allow-newer:
    diagrams-svg:base,
    diagrams-svg:containers,
    diagrams-svg:lens,
    svg-builder:base,
    diagrams-contrib:base,
    diagrams-contrib:containers,
    diagrams-contrib:lens,
    diagrams-contrib:linear,
    Chart-diagrams:lens,
    diagrams-postscript:base,
    diagrams-postscript:containers,
    diagrams-postscript:lens,
    SVGFonts:containers,
    blaze-svg:base,
    Chart:lens,

which fixed the solver issues, but it seems that we get stuck on at least building vector-space.
