When compiled for the ns32k, gas doesn't recognize an operand of
`some_label(pc)' as meaning that it should access the label via
pc-relative memory space addressing.  Instead it ignores the `(pc)' and
assembles the operand using absolute addressing.

The fix is easy.  In ns32k.c, in the function `addr_mode', add the lines:

        if (!strncmp(&str[strl-4],"(pc",3)) {
	  mode=27;
	}

right after the lines that read:

        if (!strncmp(&str[strl-4],"(sb",3)) {
	  mode=26;
	}
