Yes, the mesa3d package is quite complicated. But I believe this (at
least partially) reflects that the mesa3d configuration itself is quite
complicated. There are lots of drivers, all having special dependencies.

So, perhaps the Buildroot packaging can be improved (it would be
nice!), but it will remain anyway a complex package.
