| Subject: [PATCH] arc: define _REENTRANT when -pthread is passed |
| |
| The compiler is supposed to have the builtin defined _REENTRANT defined |
| when -pthread is passed, which wasn't done on the ARC architecture. |
| |
| When _REENTRANT is not passed, the C library will not use reentrant |
| functions, and the latest version of ax_pthread.m4 from the |
| autoconf-archive will no longer detect that thread support is |
| available (see https://savannah.gnu.org/patch/?8186). |
