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.
* config/ltmain.m4sh (func_mode_install): set new variable
`generated_by_libtool_version' in wrapper script when using

it has been subsumed into func_quote_for_eval.

were convenience libs, so we did not test the creation of shared
libraries on any platform. Also none of the libs used any actual
fortran library calls, adding a call to write(*,*) in each lib
