configure: don't enable $ARCH_external if $ARCH is disabled

Browse Source 
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.
