gprofng: 30894 bison should be no hard dependency

When running from a distribution tarball, bison should not be necessary.
The generated files (QLParser.tab.cc, QLParser.tab.hh) should be distributed.
configure.ac should not abort if bison is missing.
configure.ac should remove temporary files (dummy.c, Simple.class).
bison must be run once to create QLParser.tab.cc and QLParser.tab.hh.
