Apple reported that it was fixed in Xcode 6.3.
With Clint’s help it became clear that it is a bug in install_name_tool after all. I reproduced the issue with Xcode 6.4 and 7.0, using the same commands as at link above except adding `-arch i386 -arch x86_64` to gcc command line. Bug reported to Apple and awaits their reply. Thanks, Mike
