  To: gcc-patches, libstdc++


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.
