* tests/flags.at (passing CC flags through libtool): When $LD is used for linking libraries, ensure flags passed with `-Wc,' are not passed through to $LD, but flags passed with `-Wl,' use $wl when linking programs. Fixed testsuite failure on HP-UX 10.20. Signed-off-by: Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
