This is because you're setting LD again, by default it uses LD=gcc (and you'd pick linker with -fuse-ld=...) rather than LD=ld.lld or LD=ld. I assume you used the latter to revert from your usual lld. When testing default tools I'd suggest to unset variables rather LD=ld, LIBTOOL=libtool, {CONFIG_,}SHELL=/bin/bash, etc...
I think this is invalid per comment #4.
