Subject: tests: extend archive-in-archive with dependency forwarding check
X-Git-Url: http://git.ipfire.org/gitweb/index.cgi?a=commitdiff_plain;h=ec577ffbb3b5fc6752da7e26a23d11056a9f2cea;p=thirdparty%2Flibtool.git

tests: extend archive-in-archive with dependency forwarding check

Verify that the old library dependency is recorded in
dependency_libs of the target .la file, and that an executable
linked against the target can resolve symbols from the forwarded
dependency.
