This logic was added to libc & libm to get it working again after some reworks in the CPP handling, but now that that's settled, let's move this to the common newlib configure logic. This will make it easier to consolidate all the configure calls into the top-level newlib dir. This does create a lot of noise in the generate scripts, but that's because of the ordering of the calls, not because of correctness. We will try to draw that back down in follow up commits as we modernize the toolchain calls in here.
