sim: generate build dependencies on the fly
Lift the code that GDB is using to generate dependencies on the fly and port it over to the sim. Now people shouldn't have to manually maintain these in their Makefile's. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

+# may require accurate dependencies for correct builds, it does *not*
+# honor --disable-dependency-checking, and failure to detect a usable
