[macppc] games/hyperrogue: fix build, but colors are off

__multc3 is defined in compiler-rt, but is not built when building llvm.
So we need ports-gcc to build that port on macppc. I'm joining a diff
for that.

Runtime is fine, but colors are off: the ice is red instead of
blueish [1]. Anyone know where to start to look at?
