Comment (by tobias.netzel@…):

 Can I really seriously use Clang for targetting PowerPC OS X? Last time I
 tried it could only compile simple things and observing the development
 shows that PowerPC ELF support is improving while Mach-O support isn't at
 the same level. And the PowerPC architecture support itself doesn't seem
 to have production quality either.
