[PATCH v2] automake: add install dep on install-libLTLIBRARIES to all targets

[Jan Engelhardt]

A Makefile.am like

        bin_PROGRAMS =
        lib_LTLIBRARIES = library1.la
        pkglib_LTLIBRARIES = library2.la
        library2_LIBADD = library1.la

produces, in Makefile.in,

        install-binPROGRAMS: install-libLTLIBRARIES

but no

        install-pkglibLTLIBRARIES: install-libLTLIBRARIES

therefore potentially breaking `make install -j`. Rectify this by
depending on install-libLTLIBRARIES not just for bin_PROGRAMS, but
all PROGRAMS and LTLIBRARIES.
