Handle an edge case for minisym TLS variable lookups.
If a TLS variable is provided by a minisym from a separate debug file,
the separate debug file is passed to
gdbarch_fetch_tls_load_module_address. However, the object files
stored in the shared object list are the original object files, not
the separate debug object files. In this case,
svr4_fetch_objfile_link_map was failing to find the link map entry
since the debug object file is not in its internal list, only the
original object file.
gdb/ChangeLog:
* solib-svr4.c (svr4_fetch_objfile_link_map): Look for
objfile->separate_debug_objfile_backlink if not NULL.
