Hi,

I assume that this is for the [ldc 
group](https://forum.dlang.org/group/ldc) instead of gdc.

Generically, building druntime should be fine, you'll need a 
sufficiently old enough version of osx to run 32-bit binaries - I 
forget when they dropped multilib support, around 10.9? - which 
means that there might be some missing symbols reported when 
building Phobos (posix_memalign might be one).
