[yocto] missing "whoami" command trying to build FIT image for mpc8315e-rdb ref board

[Robert P. J. Day]

  trying for the first time to build a FIT image, so started with
current poky checkout, configured and built for mpc8315e-rdb and
core-image-minimal, everything worked fine (as it always does).

  now, as i read it, to generate a FIT image output file, i need add
only:

  KERNEL_IMAGETYPES_append = " fitImage"

to my local.conf, is that right? but this is what happens:

$ bitbake core-image-minimal

  obviously(?), selecting a FIT image triggers a call to "whoami" in
that kernel mkcompile_h script, and there is no such command in the
native sysroot. or am i doing something wrong?
