Software rendering in Replicant-4.2

[Lukas Maerdian]

Hello,

I'm right now trying to move our port of Replicant for the Goldelico
GTA04 to version 4.2.
My problem is, that the "classic" way of handling software rendering
(via vendor/replicant/config/software_gl.mk) was apparently removed in
4.2 and now the GTA04 isn't able to start the GUI, as it get's stuck
at initializing hardware rendering.

I do not want to use hardware rendering, but would rather like to
know, how software rendering is handled in the supported devices of
Replicant-4.2 and how I can include it in our GTA04 port.
I could not find any obvious changes in the other devices direcories.
So could you please point me in the right direction?

Best regards,
  Lukas
