Various libraries in this commit use the log headers (that is the
direct dependency). The log headers in turn include the T headers
(transitive dependency). Building on gracehopper with its many cores
triggers the build of these libraries before T headers have been
generated.

To resolve this and force the generation of T headers before building
the libraries, correctly express their dependency on the log headers,
which in turn ensures that T headers have been generated.

Depending on log_headers is preferrable because it is really the headers
that we depend on. Using instead e.g., utils, would trigger build of
source files, that we don't need for these libraries.  This commit is
part of a larger cleanup that I have that is not merged yet. Follow-up
work will generalize this in the repo, and ensure that every(!) library
builds.

We have to add CONFIG_LIB, as the log module has a direct dependency
onto the configuration module (it uses it). I am not sure why this was
not relevant before.
