+Fix pthread detection
+
+The latest version bump included an update to m4/ax_pthread.m4 from
+GNU autoconf which changed the way configure looks for pthread support.
+
+On Linux the macro _REENTRANT is now being searched for:
+https://github.com/peti/autoconf-archive/commit/39683064bbccb4008f239262cb681a970bf53603#diff-851a07ee321dc42003ac94cf4a9628faR211
+which fails at least on arc and blackfin.
+
+Before the autoconf update _REENTRANT was not searched on Linux:
+https://github.com/peti/autoconf-archive/commit/39683064bbccb4008f239262cb681a970bf53603#diff-851a07ee321dc42003ac94cf4a9628faL273
+
+This patch removes the check for the Linux platform by patching the
+configure script directly to avoid an autoreconf run.
