mips-elf-gcc fails to install on an M2 MacBook Air running macOS 13.2.1 with error machine arm64-apple' not recognized` in several places:

Note: I was able to successfully install i386-elf-gcc on the same system. That port is based on a much later version of gcc:

/opt/local/bin/i386-elf-gcc --version
i386-elf-gcc (GCC) 12.2.0

whereas this port is still using GCC 3.4.6.

mips-elf-gcc: map arm64->aarch64 for configure

OK, that didn't help. Probably needs to be updated, as you say.

m68k-elf-gcc seems to be in a similar situation, see #67163.
