package/mesa3d: Gallium VC4 driver depends on NEON
Since version 21.3.0 of mesa3d, the generic broadcom infrastructure
(which is called v3d but is used also for VC4) started using NEON
instructions. This leads to assembler failures when VC4 is built for
32-bit ARM without NEON:
FAILED: src/broadcom/libv3d_neon.a.p/common_v3d_tiling.c.o
/home/buildroot/autobuild/instance-2/output-1/host/bin/arm-linux-gcc [...] -c ../src/broadcom/common/v3d_tiling.c
/tmp/ccAvufNv.s: Assembler messages:
/tmp/ccAvufNv.s:602: Error: selected processor does not support `vldm r7,{q0,q1,q2,q3}' in ARM mode
[...]
/tmp/ccAvufNv.s:686: Error: selected processor does not support `vstm r7,{q0,q1,q2,q3}' in ARM mode
Let the VC4 driver depend on NEON for 32-bit ARM. Aarch64 always has
NEON, so no condition is needed there.
