uname -m says "loongarch64", the GNU triple arch name is also
"loongarch64". I'd say it's similar to the situation of RISC-V or MIPS;
except that a Linux port to the 32-bit variant of LoongArch might not
happen, precluding a QEMU port.
I think cpu=loongarch64 but ARCH=loongarch should be okay; at least it's
better than, say, the Go language or Gentoo, where this architecture is
named "loong64" and "loong"; or the binutils internals where it's "larch".
