configure: don't enable $ARCH_external if $ARCH is disabled
The check_x86asm() checks would force enable these variables on success, bypassing any --disable-* command line option. This is important in the case of AVX512, where the relevant define is used to choose between different values for memory alignment and strides in some allocations.
