Too bad :P

Well, we could spare it the multiple launches:

## Funny invocation because Makefile variable can be empty, leading to
## a syntax error in sh.
        @list='$(%DIR%_%PRIMARY%)'; for p in $$list; do \
## A file can be in the source directory or the build directory.
          if test -f "$$p"; then d=; else d="$(srcdir)/"; fi; \
## If the _%PRIMARY% variable has an entry like foo/bar, install it as
## $(destdir)/bar, not $(destdir)/foo/bar.  The user can make a
## new dir variable or use a nobase_ target for the latter case.
?BASE?    f="`echo $$p | sed -e 's|^.*/||'`"; \
?!BASE?   f="$$p"; \
          echo " $(%DIR%%PRIMARY%_INSTALL) $$d$$p $(DESTDIR)$(%NDIR%dir)/$$f"; \
          $(%DIR%%PRIMARY%_INSTALL) $$d$$p $(DESTDIR)$(%NDIR%dir)/$$f; \
        done

invokes it for each file.  Moving to the GNU Install-into-a-dir makes
this a single call, so we might actually recover some speed.
