   4 Subject: [PATCH] arc: define _REENTRANT when -pthread is passed
   5
   6 The compiler is supposed to have the builtin defined _REENTRANT defined
   7 when -pthread is passed, which wasn't done on the ARC architecture.
   8
   9 When _REENTRANT is not passed, the C library will not use reentrant
  10 functions, and the latest version of ax_pthread.m4 from the
  11 autoconf-archive will no longer detect that thread support is
  12 available (see https://savannah.gnu.org/patch/?8186).
