Comment (by bgamari):

 Austin says,
 {{{
 <thoughtpolice> bgamari: FWIW, the load commands stuff is part of dyld,
 not LLVM at all. Which makes sense because this is a dynamic linking
 problem at load time, and not one with the object linker trying to
 statically link some objects together at runtime ("Loading temp shared
 object failed..." implies it actually built the dylib).
 <thoughtpolice> The bad part about this is Apple hasn't published the new
 source code for dyld in Sierra, so there's no rhyme or reason as to why
 just yet. Look at 'ImageLoaderMachO::sniffLoadCommands' here:
 http://opensource.apple.com/source/dyld/dyld-353.2.1/src/ImageLoaderMachO.cpp?txt
 }}}
