You can't currently add arguments to FAKEROOTCMD because it is passed
as an array member to subprocess.Popen sort of like:

 subprocess.Popen([d.getVar('FAKEROOTCMD'), 'blah', 'blah', ...

In order to pass arguments, it would probably have to have split into
an array i.e. :

 subprocess.Popen(d.getVar('FAKEROOTCMD').split() + ['blah', 'blah', ...

I wasn't sure if that was desirable or if it would break anything, so
I went with the lower risk approach of adding a new variables. I can
certainly make a change to modify the usage of FAKEROOTCMD as
described above and simply append the flags to it if that is
preferred.
