+Fix usage of PTH_CONFIG to work with pthsem
+
+The pthsem re-implement of pth provides a compatibility layer for pth,
+but its pth-config script behaves slightly differently than the
+original one when reporting the version number. This patch to gnupg2's
+configure script adjusts the version checking to support this
+difference, since Buildroot uses pth-config from pthsem.
+
+We patch directly the configure script, because triggering the entire
+autoreconf dance for just a one byte change in the configure script
+seems a bit silly.
