Comment (by kencu):

 gcc10-bootstrap is supposed to use the system ld and as, so that it can be
 a freestanding compiler to build bootstrap tools without having any
 runtime deps. It was never meant to be a general-use compiler, just a
 compiler to bootstrap to general-use compilers.

 If you want it to use a different ld and as, you are meant to find a way
 to force it to do so, specifically, as part of a bootstrapping process.

 And the ancient "gas" assembler in older macos systems indeed has some
 major limitations for newer instructions.

 For the Intel path, the idea was to use gcc10-bootstrap to build
 clang11-bootstrap (which has it's own assembler) and then go from there.

 Why are we trying to build ports like nettle with gcc10-bootstrap anyway?
 Is that on a bootstrapping path?
