+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).
