+mbox: do not use backtrace if using uClibc without backtrace support
+
+Since uClibc can be configured without support for backtrace, disable
+the backtrace if we are building with a uClibc that was built without
+backtrace.
+
+This is a bit hacky, and would greatly benefit from a test in ./configure
+instead, but does nicely as a quick fix for now.
