/usr/share/mk/bsd.endian.mk:25: Unknown modifier ":aarch64 amd64 armv7 i386 powerpc64le riscv*"

Hello,

when building my world and kernel with crucial kernel modules for iGPU graphics as
defined in /etc/src.conf:

PORTS_MODULES+=         graphics/drm-kmod
PORTS_MODULES+=         graphics/drm-66-kmod
PORTS_MODULES+=         graphics/gpu-firmware-amd-kmod
...

I will receive an build error with the error shown below.
