[committed] libstdc++: Make names_pstl.cc require et tbb_backend
Checks
Commit Message
Sigh ... this test still isn't right, because it fails on systems
without a bug-fix for TBB 2020.3. We could just add -fpermissive to the
test options, but let's just require tbb_backend (which isn't matched on
systems with the buggy headers). Separately, I'm going to backport the
TBB fix to Fedora 37 where I had the test FAIL.
Tested x86_64-linux (Fedora 37 this time). Pushed to trunk.

The https://github.com/oneapi-src/oneTBB/pull/833 fix is needed for TBB
headers to avoid an error with GCC 13. The new names_pstl.cc test needs
to check effective target tbb_backend so that it's UNSUPPORTED on
systems without fixed headers.

* testsuite/17_intro/names_pstl.cc: Require et tbb_backend.

// Now we can define the macros to poison uses of non-reserved names:
