On ix86, add -Wno-format-overflow to --enable-gdb-build-warnings.

(This is a workaround for the bogus warning/error that we now see
  on i686 regarding a "may write a terminating nul past the end of
  the destination" message for the sprintf() call in
  global_symbol_searcher::search() in gdb/symtab.c.)
