That is an old MacBook with the most current "developer command line 
tools" that were available (from 2013/2014 if I remember correctly).

Sigh. Sadly I don't know enough about assembly to patch it myself :-(
But I can test because that machine is now available to me (it was 
passed to me instead of being thrown away; I did a reset, installed the 
most current software that was supported there and now try to get some 
programs running via terminal).

Note: running configure with ABI=32 (which leads to use of x86 instead 
of x86_64) leads to all files compiling and also all tests passing.
Therefore we at least know that the syntax used there including that old 
register to register workaround _does_ work correct with that assembler.

Thank you for getting back to me on this topic.
