There seems to be an issue with the RTEMS pipe() implementation or the
test configuration.

Subject: [PATCH] libstdc++: testsuite: use -lbsd for net_ts on RTEMS
Date: Wed, 22 Jun 2022 02:24:19 -0300
From: Alexandre Oliva via Gcc-patches <gcc-patc...@gcc.gnu.org>

Networking functions that net_ts tests rely on are defined in libbsd
on RTEMS, so link with it.
Regstrapped on x86_64-linux-gnu, also tested with a cross to
aarch64-rtems6. Ok to install?
for libstdc++-v3/ChangeLog
* testsuite/lib/dg-options.exp (add_options_for_net_ts): Add
-lbsd for RTEMS targets.
