It happens because --with-dynlibmodule is passed to ./configure.
Looks like the dynlibmod configure code does not include -ldl correctly
for other executables, the fix for linking on windows must have removed
that from working.  Commit with a fix that should make dynlibmod work
for other executables whilst the link of the unbound executable works
with the new link fix as well is

You could also workaround with LIBS="-ldl" on or before the ./configure
line.

Best regards, Wouter
