Yes, you should usually not use --enable-* options.
This also applies to --enable-armv6.
Configure will detect it. If it does not enable it that is because
the toolchain you selected does not support it, and forcing it will
result in exactly these errors.
It might be that you e.g. have to specify some --extra-cflags to tell
the toolchain to compile for something better than generic arm
(I think that ideally a different, more specific --target would
work, but I think it currently won't. Patches to improve things
welcome).
