At this point kvmtool compiles fines out of the Linux tree (at least
for x86 and arm/arm64), so update the README to reflect this.
Also add an INSTALL file to give more user friendly building
instructions.
Document the optional libraries and their common package names on the
way.

We should not include glibc headers from BIOS code which can't rely on glibc at
runtime.

This patch fixes the following build breakage on 64-bit:

    CC       bios/e820.o
  In file included from /usr/include/features.h:387:0,
                   from /usr/include/unistd.h:26,

  /usr/include/gnu/stubs.h:7:27: fatal error: gnu/stubs-32.h: No such file or directory compilation terminated.
  make: *** [bios/bios.bin.elf] Error 1

when built without the 'glibc-devel.i686' package on Fedora, for example.

Fix up build instructions so that people can build the tool on fresh
installation of Fedora.

This reverts commit f0aec23a91368e916a53e6072f2173bb481b1544.

  'ip=dhcp' makes kernel try to use nfs as root fs which results in a long
  time 'wait and fail' and finally fallback to 9p as root fs.

As we boot to '/bin/sh' by default, enable kernel DHCP autoconfiguration too.
The guest kernel needs to be configured with the following configuration
options:

  CONFIG_IP_PNP=y
  CONFIG_IP_PNP_DHCP=y
