The ARMTargetParser.def contains an entry for arm1176j-s which is the default
for the ArmV6K architecture. This cpu does not exist, there are only arm1176jz-s
and arm1176jzf-s and they are both architecture ArmV6KZ. The only CPUs that are
actually ArmV6K are the mpcore, mpcore_nofpu and later revisions of the arm1136
family r1px (which we don't have a table entry for).
