[macppc] Unbreak games/cataclysm-dda

Hi,

It was expected to happen one day :)

From the current macppc bulk:

> obj/tiles/active_item_cache_test.o: In function `::_ZL29____C_A_T_C_H____T_E_S_T__(void)':
> active_item_cache_test.cpp:(.text+0x1b4): relocation truncated to fit: R_PPC_PLTREL24 [...]
> active_item_cache_test.cpp:(.text+0xcb4): additional relocation overflows omitted from the output

The below diff allowed me to build CDDA [0].

Runtime test: it is slow, but OK.

LDFLAGS is empty and this version has never been built on macppc, so
REVISION bump is not needed.

Comments/feedback are welcome,

Charlène.
