I'm confused.
Background: the only reason you ever need a wrapper script for an
executable in a libtoolized project, is when that executable depends on
an uninstalled shared library. You need the wrapper script to set PATH
(and LD_LIBRARY_PATH on other platforms) so that the runtime loader can
find the shared library.
BUT, if you do not depend on any (uninstalled) shared libraries, then
you don't need a wrapper script...so it shouldn't be created at all, and
the "real" executable should be in the build directory, not in .libs/

This comes from this fragment:
if test \"\$libtool_install_magic\" = \"$magic\"; then
# install mode needs the following variable:
notinst_deplibs='$notinst_deplibs'
else

Right. This is part of the integrity checks built in to libtool --
since the ONLY thing you know about any exe wrapper script is it darn
well better define noninst_deplibs (otherwise, there should be no
wrapper). So, to check that it successfully sourced something that WAS
in fact a wrapper script, libtool tries to make sure that
notinst_deplibs got set. ('cause if it didn't, then there are probably
other significant problems, like an incorrect $relink_cmd, etc)
In your case, you have a wrapper script -- but an empty noninst_deplibs.
One of two things is true:
(1) your exe really truly does not depend on any uninstalled libraries.
--> so need to investigate WHY a wrapper script was created at all.
or
(2) your exe DOES have uninstalled library dependencies
--> so need to investigate WHY they went unrecorded in the wrapper.
Needless to say, I haven't observed that behavior here.
BTW, does your version of libtool contain this ChangeLog entry?

* config/ltmain.m4sh (func_mode_link): don't relink
on cygwin/mingw; no need. But do ensure that wrappers
are created unless doing a purely static build.
'cause it touches exactly this bit of code.
