Building the experimental sys-devel/gdb-13.0.91 has the same problem. What's going on? Is it an ebuild bug, or is it simply unsupported? Full emerge output is attached.
Confirmed. It's an upstream problem. Apple M1 (AArch64) is supported by gdb when running Linux, but not on macOS currently. https://inbox.sourceware.org/gdb/3185c3b8-8a91-4beb-a5d5-9db6afb93713@Spark/
