Subject: [PATCH v3 8/8] Makefile: Add loongarch target flag for Clang compilation

From: WANG Xuerui <git@xen0n.name>

The LoongArch kernel is 64-bit and built with the soft-float ABI,
hence the loongarch64-linux-gnusf target. (The "libc" part can affect
the codegen of libcalls: other arches do not use a bare-metal target,
and currently the only fully supported libc on LoongArch is glibc
anyway.)
