Log:
  add -znotext to kernel module link invocation
  
  ARM kernel modules require .text relocations (DT_TEXTREL) in shared
  object ouptut, which is not allowed by default by lld.  Add the -znotext
  option to enable this.  For simplicity add it unconditionally: it is
  already default and thus either redundant (GNU BFD ld and gold from
  ports) or ignored as an unknown option (GNU BFD ld 2.17.50 in the base
  system).
