  Log Message:
  -----------
  [ELF] -r: don't define _TLS_MODULE_BASE_

_TLS_MODULE_BASE_ is supposed to be defined by the final link. Defining it in a
relocatable link may render the final link value incorrect.

GNU ld i386/x86-64 have the same issue: https://sourceware.org/bugzilla/show_bug.cgi?id=29820
