Well, that's my question: what _does_ work?

I have OS X 10.10.5 (Yosemite) and no wish to upgrade,
so pointers on where to get proper Xcode, Command line tools etc. would 
help.

Here are the details and errors for two builds, 1) with GCC/LLVM 
(/Developer/usr/bin/cc) and 2) with LLVM/CLANG (/usr/bin/cc).

Short:
1) /Developer/usr/bin/cc:
   error: 'LONG_MIN' undeclared
   in tools/binutils

2) /usr/bin/cc:
   Undefined symbols for architecture x86_64: "_iconv"
   in external/gpl3/gcc/usr.bin/backend


Long:

1) /Developer/usr/bin/cc: error: 'LONG_MIN' undeclared
