Add missing CLANG_TARGET_FLAGS_loongarch and RUST_TARGET_FLAGS_loongarch
so that perf can be built with clang and enable rust cross compilation.

FWIW, sounds good. I guess the commit that added the list should have
had it to begin with? Cc Dmitrii.

Yep, it should have -- as far as I can tell perf supports loongarch in
all the other ways. Unfortunately I based my patch on
CLANG_TARGET_FLAGS, which turned out to be missing this arch as well.
