adjustable.

Commit eb90831ce8 added it to the wrong
makefile.

Previously, when compiling files in parallel like Guix does, threads
would be concurrently inserting, rehashing, and reading the submodule
hash table of module (). Thus, some threads would sometimes see an
inconsistent state, leading to errors such as:
