kernel-arch.bbclass: Do not use weak assignment for TOOLCHAIN

If a distro sets TOOLCHAIN with ?= or = then it overrides this
too, however, we demand GCC to be in there due to KERNEL_CC etal
Make it hard assignment, it can still be overturned via a bbappend
in that case it is intentional to use non-gcc compiler for kernel
