dynamically linked build

[barter-simsum]

The old build system dynamically linked debug builds by default. We can't currently easily do this with bazel.

I would like the ability to specify desired linking type when building because a dynamically linked build is far more flexible a thing in the development cycle -- primarily because of what's possible with LD_PRELOAD -- load a profiler, load an alternative implementation of a library (e.g. malloc) and compare its results to previous, etc.

I imagine this will require making the arg to the linkstatic params in many of our cc_librarys configurable rather than statically True. Need to also understand instances of:

    features = select({
        "@platforms//os:linux": ["fully_static_link"],
        "//conditions:default": [],
    }),

It may be easier to avoid bazel altogether and just adopt the old Makefile vere used to the new repo structure

I have a CMake configuration almost working...
