What about the packages that select some libdrm drivers? I'm thinking
for example of:

config BR2_PACKAGE_MESA3D_DRI_DRIVER_NOUVEAU
        bool "DRI nouveau driver"
        select BR2_PACKAGE_MESA3D_DRI_DRIVER
        select BR2_PACKAGE_LIBDRM_NOUVEAU
        help
          Support for Nvidia-based GPUs.

config BR2_PACKAGE_MESA3D_DRI_DRIVER_RADEON
        bool "DRI radeon driver"
        select BR2_PACKAGE_MESA3D_DRI_DRIVER
        select BR2_PACKAGE_LIBDRM_RADEON
        help
          Legacy Radeon driver for R100 series GPUs.

Best regards,

Thomas
