#
# Check that symbol scope is demoted to local when external symbols are
# converted to absolutes. This is demotion is necessary to avoid "unexpected
# definition" errors.
#
# The reference to _GLOBAL_OFFSET_TABLE_ will trigger creation of an external
# _GLOBAL_OFFSET_TABLE_ symbol, and the GOTOFF relocation will force creation
# of a GOT symbol without actually introducing any GOT entries. Together these
# should cause the external _GLOBAL_OFFSET_TABLE_ symbol to be converted to an
# absolute symbol with address zero. If the scope is not demoted correctly this
# will trigger an "unexpected definition" error.
