UML makefiles sanitized:
- number of generated headers reduced to 2 (from user-offsets.c and
kernel-offsets.c resp.). The rest is made constant and simply
includes those two.
- mk_... helpers are gone now that we don't need to generate these
headers
- arch/um/include2 removed since everything under arch/um/include/sysdep
is constant now and symlink can point straight to source tree.
- dependencies seriously simplified.

Even if with a bit of misunderstanding, Al fixed this in commit
95608261da.
Well, the symbol was intended to come from userspace (it exists there on normal
host), but since some hosts may miss that, using the kernel one is just as fine.
However, rename it to be named consistently with the rest.
Actually, he missed converting ELFCLASS32 to coming from kernel headers. For
consistence, add ELFCLASS64 too.

asm/elf.h is bad on x86_64, and i386 doesn't need it any more after Al's

elf_aux is userland code; it uses symbol (ELF_CLASS) that doesn't exist in
userland headers; pulled into kernel-offsets.h, switched elf_aux to using it.

The #if/#ifdef cleanup exposed a bug in UML's ELF header processing. With
this bug fixed, UML recognizes the vsyscall info coming from the host. On
FC4, there is a vsyscall page low in the address space, which UML doesn't
provide. This causes an infinite page fault loop and a hang on boot.
This patch works around that by making this look like a no-vsyscall system.

This is a bunch of compile fixes provoked by building UML with gcc 4. There
are a bunch of signedness mismatches, a couple of uninitialized references,
and a botched C99 structure initialization which had somehow gone unnoticed.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
