compiling git -85rc

[Michael Tokarev <mjt@tls.msk.ru>]

For quite some time the compilation of userspace is
broken on my environment.  I'm not sure if it's new
or it was this way before -- at least kvm-84 builds
fine.

The problem happens when the kernel running is 64bits
and the userspace is 32bits.  In the source tree,
qemu/ directory correctly configures itself to use
-m32 compiler flag (the default anyway), but other
directories -- libkvm/ and user/ uses x86_64 for
$(ARCH) and hence -m64 and /lib64.  And sure thing,
the link stage does not work because -lkvm is not
compatible (32 vs 64 bits).

I had to change
  include config-$(ARCH).mak
into
  include config-i386.mak
in libkvm/Makefile and in user/Makefile to build it.

Maybe, just may be, it's sufficient to do a
  make ARCH=i386
step instead - I'll try that too.

Comments?

Thanks.
