Willy,

Is there a way to make it work for the default qemu installation?
Or maybe it's a mandatory requirement to build qemu from the source?

I use the qemu that comes from Ubuntu apt. I have "qemu-system-x86_64",
but no "qemu-x86_64". So, something like this...

  $ which qemu-x86_64
  $ echo $?
  1

  $ which qemu-system-x86_64
  /usr/bin/qemu-system-x86_64

  $ time make run-user
    MKDIR   sysroot/x86/include
  make[1]: Entering directory '/home/ammarfaizi2/work/linux.work.cc/tools/include/nolibc'
  make[2]: Entering directory '/home/ammarfaizi2/work/linux.work.cc'
  make[2]: Leaving directory '/home/ammarfaizi2/work/linux.work.cc'
  make[2]: Entering directory '/home/ammarfaizi2/work/linux.work.cc'
    INSTALL /home/ammarfaizi2/work/linux.work.cc/tools/testing/selftests/nolibc/sysroot/sysroot/include
  make[2]: Leaving directory '/home/ammarfaizi2/work/linux.work.cc'
  make[1]: Leaving directory '/home/ammarfaizi2/work/linux.work.cc/tools/include/nolibc'
    CC      nolibc-test
  /bin/sh: 1: qemu-x86_64: not found
  0 test(s) passed.

  real    0m0.506s
  user    0m0.393s
  sys     0m0.086s

It would be great if we can avoid building qemu from the source. But if
not, let's go with that.

Thanks!
