[libtool 2.2] testsuite: 55 failed with as-needed

[Alexis Ballier]

Hi,

Perhaps it's the desired behavior, but I get a failure on test 55 when
using -Wl,--as-needed in LDFLAGS (and its ok if I remove it).
From my poor understanding of template.at, the test is run for the case
when libb does not depend on liba and when linking the main program
against both libb and liba, liba gets dropped but libb needs it, thus
the linking failure. Anyway, I thought it was worth reporting it.

(log below)

Regards,

Alexis.
