<pre>lld gives warning to unknown flag like -no-such-flag,
but does not give warning to unknown -z option like -z,no-such-flag.
$ ./clang -fuse-ld=lld -Wl,-no-such-flag /tmp/m.o -o /tmp/a.out
.../bin/ld.lld: error: unknown argument: -no-such-flag
clang-7: error: linker command failed with exit code 1 (use -v to see
invocation)
$ ./clang -fuse-ld=lld -Wl,-z,no-such-flag /tmp/m.o -o /tmp/a.out
Some GNU linker -z options such as -z,global is not implemented in lld yet,
but lld does not give warning to such options.</pre>
