kvmtool is a lightweight tool for hosting KVM guests.
As a pure virtualization tool it only supports guests using
the same architecture, though it supports running 32-bit guests
on those 64-bit architectures that allow this.

# This is required to convert a static binary (init helper) back into
# object-file format, and in multilib toolchains like CS 2012.09 for x86
# the default is i386, hence when building for x86_64 things break since
# LD doesn't autodetect the input file format.
# GCC-as-linker can't accomplish this feat easily either since it's mixing
# static content (guest_init.o) with dynamic one (lkvm) making
# a relocatable output file.
# The purpose of this trick is to embed the init helper into the main
# binary to help users in guest system startup, which would otherwise
# require more complex guest images.
# This needs revisiting if/when X32 ABI support is added.
#
# If more packages need this (unlikely) an ld wrapper might be a better
# solution, using gcc -dumpspecs information.
