[bug#74522] [PATCH 20/73] move libgl provider from mesa to libglvnd+mesa

[The Man <squishypinkelephant@gmail.com>]

I'm not a complete expert on the topic but the general consensus is
that libglvnd is expected to be used.
mesa's upstream defaults to compiling with libglvnd support (if it can
find it. i didn't see much success, only tried once... , simply adding
libglvnd as an input)
even with nvidia moving towards open source for once I hard suspect
they will default to the libglvnd expected packaging style, with very
few distributions being similar to guix (with the libgl provider is a
single vendor)
