  Unable to build kvm-unit-test on i386 system

Status in ubuntu-kernel-tests:
  Fix Released
Status in linux package in Ubuntu:
  Invalid

Bug description:
  When trying to build the kvm-unit-test on i386 node, it will fail
  with:

    gcc  -m32 -O1 -g -MMD -MF lib/x86/.usermode.d -Wall -Wwrite-strings -Wclobbered -Wempty-body -Wuninitialized -Wignored-qualifiers -Wunused-but-set-parameter -Werror  -fno-omit-frame-pointer    -Wno-frame-address   -fno-pic  -no-pie -Wmissing-parameter-type -Wold-style-declaration -Woverride-init -ffreestanding -I /home/ubuntu/autotest/client/tmp/ubuntu_kvm_unit_tests/src/kvm-unit-tests/lib -I lib   -c -o lib/x86/usermode.o lib/x86/usermode.c
    <builtin>: recipe for target 'lib/x86/usermode.o' failed
    stderr:
    lib/x86/usermode.c: In function ‘run_in_user’:

      ^~~
    make: *** [lib/x86/usermode.o] Error 1

  Steps:
    1. git clone --depth=1 https://git.kernel.org/pub/scm/virt/kvm/kvm-unit-tests.git
    2. ./configure
    3. make

  This is a test suite issue, not a regression, as it can be reproduced
  on 4.13.0-38
