[Buildroot] [PATCH 3/4] package/llvm: add AMDGPU support

[Valentin Korenblit]

From: Romain Naour <romain.naour at gmail.com>

Limit the number of supported target for mesa3d when openCL support is enabled.
With -DLLVM_TARGETS_TO_BUILD="all" mesa3d fail to build on x86_64 target with AMDGPU target:
