[Mesa-dev] Drop scons for 20.1?

[Marek Olšák]

In the long term we should reduce the complexity of the project. scons is a
maintenance burden. Every time I break the scons build and the CI reports
it, can I politely ask you to fix my MR instead of me doing it? Then at
least the real maintenance cost would be known to scons supporters, instead
of the cost being invisible to most.

In the mean time, I think we can remove all parts of scons that VMWare does
NOT care about. Do you need haiku-softpipe? Do you need graw-null? Do you
need swr? glx? There is bunch you don't really need on Windows.
