The build echos all of the known variables that get passed in the
ENV environment. One of those variables should be SYS.

The SYS variable is the last symbol of the AXIOM shell variable as in:

  export AXIOM=`pwd`/mnt/linux

   ==>

  SYS=linux

so potentially you did a 'make' in a shell that had the AXIOM variable set
and then did 'make install' in a new shell without the AXIOM variable set.

The sudo almost certainly did not copy your AXIOM shell variable.

I'll have to give this some thought.
