Comment (by harens):

 > Unfortunately, it fails likewise.

 I know this might not seem like it, but this is good news. We've fixed the
 `-no-pie` error and moved on to a different error. These are baby steps to
 success my friend :)

 Our current error is the following, which also happened on 10.6 PPC
 previously:

 {{{
 /opt/local/lib/gcc6/gcc/ppc-apple-darwin9/6.5.0/include/stdatomic.h:40:1:
 sorry, unimplemented: '_Atomic' in Objective-C
 typedef _Atomic _Bool atomic_bool;
 }}}

 The problem is that I still don't know how to fix this. Give me some time
 to think about this...
