I believe lld supports TLSDESC for ARM64 because it's the default TLS access model on ARM64. The comment here says that `_TLS_MODULE_BASE_` is defined for targets that support TLSDESC. But the `if` condition includes only i386 and x86-64. It doesn't seem correct. Not directly related to this change, though.
