ARM: disallow pre-ARMv5 builds with ld.lld

lld cannot build for ARMv4/v4T targets because it inserts 'blx' instructions
that are unsupported there:

  ld.lld: warning: lld uses blx instruction, no object with architecture supporting feature detected

Add a Kconfig time dependency to prevent those targets from being
selected in randconfig builds.
