[macppc] Unbreak games/scummvm

Hi,

> http://build-failures.rhaalovely.net/powerpc/2020-12-15/games/scummvm.log

Classic relocation issue, i should have provided that fix earlier.

With the below diff, scummvm builds on macppc [0]. I also successfully
tested the runtime playing Beneath a Steel Sky (games/bass).

No REVISION bump is needed; this version has never been built on macppc,
and ${LDFLAGS} is empty on other archs.

OK?

Charlène.
