Rather than this:

nobase_pkgdata_DATA += frysk/pkgdatadir/test-sysroot/usr/lib/debug/$(abspath
frysk/pkglibdir/fu
nit-addresses.debug)
frysk/pkgdatadir/test-sysroot/usr/lib/debug/$(abspath
frysk/pkglibdir/funit-addresses.debug): f
rysk/pkgdatadir/test-sysroot/$(abspath frysk/pkglibdir/funit-addresses)
        mkdir -p $(abspath
frysk/pkgdatadir/test-sysroot/usr/lib/debug/)/$(abspath frysk/pkglib
dir)
        eu-strip --remove-comment -f $@ $<

install-data-hook:
        mv $(datarootdir)/frysk/frysk/pkgdatadir/test-sysroot $(datarootdir)/frysk
        rmdir $(datarootdir)/frysk/frysk/pkgdatadir
        rmdir $(datarootdir)/frysk/frysk
# we don't want this installed, but noinst_SCRIPTS has no effect
        rm $(libdir)/frysk/gen-type-funit-tests

do something like this:

install-data-local: install-dogtail-scripts-local
uninstall-local: uninstall-dogtail-scripts-local
.PHONY: install-dogtail-scripts-local uninstall-dogtail-scripts-local
install-dogtail-scripts-local:
        set -e ; \
        ( \
                cd $(srcdir)/frysk/gui/test ; \
                find dogtail_scripts \
                        -name CVS -prune \
                        -o -type f -print \
                | tar cTf - - \
        ) | ( \
                cd $(DESTDIR)$(pkgdatadir) ; \
                tar xpf - \
        )
        cp -p -f frysk/gui/test/dogtail_scripts/frysk_suite.py \
                $(DESTDIR)$(pkgdatadir)/dogtail_scripts
uninstall-dogtail-scripts-local:
        rm -rf $(DESTDIR)$(pkgdatadir)/dogtail_scripts
