configurator: more robust test for HAVE_NESTED_FUNCTIONS

Thanks to Andreas Schlick, we have a nicer test for when gcc warns about
trampolines (gcc 4.6's -Wtrampolines).  This works at any optimization level,
and means when that warning is enabled we recognize that we shouldn't allow
nested functions.
