| 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. | |||||
