Sometimes, a wrapper script is generated for an executable that, itself,
does not link against an uninstalled library. It appears that this can
happen if you are building a project where
(1) there is a library
(2) there is an executable that does not, itself, link against that
library
In this case, notinst_deplibs is empty, and when the wrapper script is
loaded by libtool during ./libtool mode=install, there is a check for
is notinst_deplibs empty. In this case, it is, so libtool reports an
error.
I don't think it is wrong to have a wrapper script for an exe that
*technically* doesn't need it. But instead of checking for
notinst_deplib nonempty as a proxy for did wrapper script get sourced
into my environment properly a different var should be used.

Attached patch (by Peter Ekberg) has no regressions on cygwin.

* config/ltmain.m4sh (func_mode_install): set new variable
'generated_by_libtool_version' in wrapper script when
libtool_install_magic. When verifying that wrapper script
was properly sourced, check that generated_by_libtool_version
is nonempty, instead of notinst_deplibs.
