[OE-core] [PATCH 2/2] mesa: make gallium swrast target optional

[Marco Felsch]

Most the time we are compiling for embedded targets which have dedicated
hardware combinations. Setting swrast default on isn't a good solution
for such devices because if the hardware render node have an issue or
don't support a special format/request mesa will fallback to the software
renderer. This will make it harder to debug performace issues.

A better way is to let the user deciced if a software renderer is
needed e.g. if the system has no hardware renderer or to have such a
fallback device. This way the user knows that the software renderer is
enabled.
