[PATCH] [lld] [ELF] Support for general dynamic TLS relocations on X86_64

[Rafael Auler]

For example, if you strace the GNU ld when linking a TLS library, it will never open "ld.so". This suggests that the ELF linker should be self-contained with respect to the symbols of ld.so, providing hardwired definitions of them.
