Subject: Move to a shared static RWX section

Does away with the need to mark a region as executable on load.
Also allows the self-modified stuff and hook trampolines to fit in the
same page, so we take up ever-so-slightly less memory.

Unfortunately I had issues getting the test binary to build correctly
and eventually decided to give up as it wasn't testing much of value
anyway.

Also note that the build now allows for .c and .S files with the same
basename, which required renaming the .o files, so you might want to
clean out your .build/ directory before building this one.
