libctf, ld: fix data symbol test with newer GCC
GCC 11+ spots that the extern var_1 and var_666 declarations in this
test are unused, and removes them, thus stopping them from appearing as
conflicted data symbols and rendering the test pointless. Use them in a
function unique to this TU to prevent them from being eliminated.
ld/ChangeLog
2021-01-19 Nick Alcock <nick.alcock@oracle.com>
* testsuite/ld-ctf/data-func-2.c: Stop removal of the extern foo_t
symbols by the optimizer.
* testsuite/ld-ctf/data-func-conflicted.d: Adjust accordingly.
