I have a series of patches on top of this (on the next branch), but I was planning to get this initial support in first. Possibly my "Fixed initialisation code" commit should be merged with Karim's code into a single patch. On the other hand, it might be clearer to keep them separate (especially for other people who have built on Karim's original work, e.g. I see on github that Jonathan Daugherty has a fork from there).

Without HAVE_LIBC, minios provides its own versions of some basic functions (memcmp, sprintf, etc). Mirage works without it, for example. > 2.
