[Octave-bug-tracker] [bug #58689] [MXE Octave] Update mesa to use meson as (native) build tool

[Markus Mützel]

Follow-up Comment #6, bug #58689 (project octave):

I tried to update build-python to python3 (python3.patch).
With that, ninja and meson compiled fine (build-ninja_v2.patch and
build-meson_v2.patch).

Unfortunately, scons needs python 2.7 and is incompatible with python3. Thus,
the native build rule for mesa broke.
I figured that this wouldn't be too bad after all because we wanted to change
to meson anyway. (Primarily as the native build tool. But using the same build
tool for cross and native builds would probably not hurt imho.)

It turns out meson needs llvm-config to be able to detect llvm
(llvm_config.patch).

But I am still stuck at trying to cross-compile mesa with meson.
The build seems to work ok. But at the last step, it fails with the following
linker error:

These libraries shouldn't be linked in for a win32 library. (At least dl, rt,
and tinfo wouldn't work pretty certainly. Not so sure about xml2.)
I don't know where these flags come from. Any help would be very much
appreciated.
