 > Irrlicht fail to detect properly the NEON support on aarch64 or ARM with NEON FPU support.

 > Some files are missing in the libpng bundled in Irrlicht, in particular arm/arm_init.c [1],
 > so disable NEON support completely.

 > This can be reproduced by building minetest using this defconfig for aarch64:

 > BR2_TOOLCHAIN_EXTERNAL=y
 > BR2_PACKAGE_MINETEST=y
 > BR2_PACKAGE_MINETEST_CLIENT=y
 > BR2_PACKAGE_MINETEST_SERVER=y
 > BR2_PACKAGE_MESA3D=y
 > BR2_PACKAGE_MESA3D_GALLIUM_DRIVER_SWRAST=y
 > BR2_PACKAGE_MESA3D_OPENGL_GLX=y
 > BR2_PACKAGE_XORG7=y

 > Or for ARM with NEON FPU support:
 > BR2_arm=y
 > BR2_cortex_a15=y
 > BR2_ARM_FPU_NEON=y
 > BR2_TOOLCHAIN_EXTERNAL=y
 > BR2_PACKAGE_MINETEST=y
