Using two temporary directories for the generation of “ocamlbuild_pack.cm*”

[elfring]

The directory “tmp” is created by two recipes in the make script which is used so far. I imagine that this approach can become insufficient in the use case that a software build would be attempted in parallel.

How do you think about the possibility to work with two temporary directories for the generation of the desired file variant “ocamlbuild_pack.cm[ox]”?

Sure, makes sense.
