[PATCH] libstdc++: Fix up 19_diagnostics/stacktrace/hash.cc on 13 branch

[Jakub Jelinek]

Hi!

The r13-8207-g17acf9fbeb10d7adad commit changed some tests to use
-lstdc++exp instead of -lstdc++_libbacktrace, but it didn't change
the 19_diagnostics/stacktrace/hash.cc test, presumably because
when it was added on the trunk, it already had -lstdc++exp and
it was changed to -lstdc++_libbacktrace only in the
r13-8067-g16635b89f36c07b9e0 cherry-pick.

The test fails with
/usr/bin/ld: cannot find -lstdc++_libbacktrace
collect2: error: ld returned 1 exit status
compiler exited with status 1
FAIL: 19_diagnostics/stacktrace/hash.cc (test for excess errors)
without this (while the library is still built, it isn't added in
-L options).

Ok for 13 branch?

I think the r13-8067 cherry-pick hasn't been applied to 12 branch,
so we don't need it there.
