Fixed compiler warnings

Fixed random failure in test system

BUILD/compile-solaris-sparc:
  Addex EXTRA_FLAGS to configure line (to get rid of warnings for not initialzed variables on buildbot)
cmd-line-utils/libedit/filecomplete.c:
  Remove not used variables
mysql-test/suite/rpl/r/rpl_optimize.result:
  Updated result
mysql-test/suite/rpl/t/rpl_optimize.test:
  Use sync_salve_with_master to ensure cleanup on slave
support-files/compiler_warnings.supp:
  Added suppression of libedit files
