Details:

In MXE Octave, we use autotools to build mesa on Linux natively.
Mesa has dropped support for autotools in later versions. So we are stuck at
version 19.0.8.

I tried to add build rules for meson with the goal to switch to meson for
building mesa.

Meson depends on ninja.

I was able to make some changes to build ninja (see attached patch
build-ninja.patch).

But building meson (see attached patch build-meson.patch) fails early on
with:

ERROR: Tried to install Meson with an unsupported Python version: 
2.7.15 (default, Jun 11 2020, 17:37:14) 
[GCC 9.3.0]
Meson requires Python 3.5.2 or greater


Is it possible to update python to python3? Or would that break a lot?

Even if building meson should succeed, I have not yet tried to build mesa with
meson.

Needless to say that all of this is very preliminary.

Any help would be appreciated.
