a fixup is $global$ change it to NULL as $global$ is really only
needed long enough to determine the base type of relocation to use.

Consistently set return value to -1 for an error. Clean up error

(machine_ip): When handling case 'i' or 'A', make sure that the
appropriate opcode really exists by looking at the next entry in
the opcode table.
