muniversal does not support overridden destroot blocks. It requires the ability to run the "destroot" cmd, for example using its default cmd "make" and its default target "install". It's always been that way. It is occasionally inconvenient, but the workaround of writing a short Makefile has apparently always been preferable to figuring out how to rewrite muniversal to not have this requirement.
