From 4c6367c99461fdd7bd5613483f2582d7f08fba87 Mon Sep 17 00:00:00 2001 From: Vlad Zakharov Date: Tue, 28 Feb 2017 17:41:11 +0300 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).
