[ Upstream commit 1632936480a53d85ef3012cd9f290e247251cbb9 ]
When we don't have the iputils-debuginfo package installed, i.e. when we
don't have the DWARF information needed to resolve ping's samples, we
end up failing this 'perf test' entry:
# perf test ping
62: probe libc's inet_pton & backtrace it with ping : Ok
# rpm -e iputils-debuginfo
# perf test ping
62: probe libc's inet_pton & backtrace it with ping : FAILED!
#
Fix it to accept "[unknown]" where the symbol + offset, when resolved,
is expected.
I think this will fail in the other arches as well, but since I can't
test now, I'm leaving s390x and ppc cases as-is.
