temp/libdrm-grate: build all drivers, not just tegra

Minecrell requested to merge Minecrell/pmaports:make-libdrm-grate-great-again into master

Fixes pmbootstrap#1868 (closed)

At the moment, installing the rootfs for ouya-ouya fails with:

Looking closer at the error we see that:

  1. We want to explicitly install libdrm-grate for device-ouya-ouya.
  2. libdrm-grate provides
    • so:libdrm.so.2=2.4.0
    • so:libdrm_tegra.so.0=0.0.0
    • so:libkms.so.1=1.0.0
  3. But the mesa package also builds AMD and Nouveau drivers and therefore requires:
    • so:libdrm_amdgpu.so.1
    • so:libdrm_nouveau.so.2
    • so:libdrm_radeon.so.1

These libraries are not provided by libdrm-grate, therefore it is impossible to install mesa and libdrm-grate at the same time.

A simple solution to fix this problem is to let libdrm-grate provide these additional libraries as well - the package size overhead is negligible and the additional drivers build just fine.
