Well, we don't have an end-all be-all solution to this issue yet.
I babbled about an idea to solve this a while ago in
but never got around to an actual implementation.

Yeah, you can avoid changing in your workaround
by hiding the target name in a variable:

  inst_execenv_libs = install-execenvLTLIBRARIES
  $(inst_execenv_libs): install-libLTLIBRARIES

But of course you are still invading Automake private namespace, and
exploiting the bug that automake does not "see" through variables for
rule target names.  I suppose that we might break your hack with the
Automake version that will finally provide a solution for this.

BTW, strictly speaking, you are also missing a opposite workaround for
the uninstall rule (just in case your "make uninstall" is racing with,
or uses programs that use these libraries, and you have an older, say
incompatible, set of libraries lying around as well).
