sim: use ## for automake comments The ## marker tells automake to not include the comment in its generated output, so use that in most places where the comment only makes sense in the inputs.

sim: hoist mn10300 & v850 igen rules up to common builds These rules don't depend on the target compiler settings, so hoist the build logic up to the common builds for better parallelization. We leave the mips rules in place as they depend on complicated arch-specific configure logic that needs to be untangled first.

sim: mn10300: move libsim.a creation to top-level The objects are still compiled in the subdir, but the creation of the archive itself is in the top-level. This is a required step before we can move compilation itself up, and makes it easier to review. The downside is that each object compile is a recursive make instead of a single one. On my 4 core system, it adds ~100msec to the build per port, so it's not great, but it shouldn't be a big deal. This will go away of course once the top-level compiles objects.

sim: run: move linking into top-level Automake will run each subdir individually before moving on to the next one. This means that the linking phase, a single threaded process, will not run in parallel with anything else. When we have to link ~32 ports, that's 32 link steps that don't take advantage of parallel systems. On my really old 4-core system, this cuts a multi-target build from ~60 sec to ~30 sec. We eventually want to move all compile+link steps to this common dir anyways, so might as well move linking now for a nice speedup. We use noinst_PROGRAMS instead of bin_PROGRAMS because we're taking care of the install ourselves rather than letting automake process it.

sim: build: hoist lists of hw devices up We need these in the top-level to generate libsim.a, but also in the subdirs to generate hw-config.h. Move it to the local.mk, and pass it down when running recursive make. This avoids duplication, and makes it available to both. We can simplify this once we move the various steps up to the top-level too.

sim: build: move generated headers to built sources Automake's automatic header deptracking has a bootstrap problem where it can't detect generated headers when compiling. We've been handling that by adding a custom SIM_ALL_RECURSIVE_DEPS variable, but that only works when building objects recursively in subdirs. As we move those out to the top-level, we don't have any recursive steps anymore. The Automake approach is to declare those headers in BUILT_SOURCES. This isn't completely foolproof as the Automake manual documents: it only activates for `make all`, not `make foo.o`, but that shouldn't be a huge limitation as it only affects the initial compile. After that, rebuilds should work fine.

sim: modules: trigger generation from top-level Add rules for tracking generated subdir modules.c files. This doesn't actually generate the file from the top-level, but allows us to add rules that need to be ordered wrt it. Once those changes land, we can rework this to actually generate from the top-level. This currently builds off of the objects that go into the libsim.a as we don't build those from the top-level either. Once we migrate that up, we can switch this to the source files directly. It's a bit hacky overall, but makes it easier to migrate things in smaller chunks, and we aren't going to keep this logic long term.
