With the TLS runtime landed (PT_TLS loading + per-thread FS base) and tls-test.elf passing on the OS, the sysdep.h hunk that degraded BFD's _Thread_local error state to plain globals is no longer needed. Native binutils is rebuilt with genuine thread-locals: the shipped tools now carry a PT_TLS segment and %fs-relative accesses, exercising the new runtime in every invocation.
