Ok there are a number of things that need to be done that I do not
have time to do and am unlikely to have time to do them in the near
future.
These are currently being left in the hope that users will do them
instead.

1. replace netinet/in_cksum.c with an assembly version
2. replace netns/ns_chsum.c with an assembly version
3. drivers for currently unsupported podules
4. replacing the C string functions in libc with assembly ones (work
   started but not finished)
5. porting libpthread to arm32 architecture
