libtool: Add no-undefined flag based on host OS

Without the no-undefined flag, the test will fail on Mingw and
Cygwin, so the flag will be appended for windows compilation. With
the flag, the test will fail on NetBSD, so the flag is removed.

* tests/bug_62343.at: Add no-undefined flag for windows-based
  compilation and remove otherwise.
