+Subject: [PATCH] configure.ac: fix error with version string

+Put version string in square brackets to satisfy autoconfigure.

+	  ply is a light-weight dynamic tracer for Linux. By means of
+	  using the BPF it can attach probes to the linux kernel
+	  (e. g. kprobes).
+
+	  It's a small alternative to LLVM based tracers for embedded
+	  systems.
+
+	  When using debugfs needs to be mounted on /sys/kernel/debug.
