changed the description

Please review, @ben.boeckel. Please start relevant testing if you think it is necessary.

Patch from https://discourse.paraview.org/t/building-paraview-5-7-0-and-5-8-0-on-the-power-9-architecture-under-linux-update/4364.

Patch submitted upstream to https://github.com/markcmiller86/silo-issues/issues/207.

@chuck.atkins @utkarsh.ayachit I don't mean to exclude you from the review fun.

Seems reasonable.

+1 if it patches properly on non-Windows for you (no need to waste buildbot's time testing that)

Yup, patches property on non-Windows build locally. Thanks!

Do: merge
