[Buildroot] [git commit] package/mesa3d: add dependency on elfutils for R600 with LLVM

[Michał Kalbarczyk]

Hi,
Just figured out that you're creating a PR with gallium R600 driver. I'm
trying do the same thing with RADEONSI driver.
Can you add radeonsi driver to your PR, or should I create separate PR for
that ?

thanks for your help
Michał.
