Not important, just a cosmetic one.

This is to revert the order of PR and MACHINE_KERNEL_PR assignments, so it 
works when machine_kernel_pr.bbclass is not inherited (i.e. for distros other 
than Arago or Angstrom)...

This moved to cmem.inc

Ok, this is the major change - module.bbclass already provides do_compile() 
and do_install() functions with most of the code in there. All we need is to 
pass few additional variables.

This is the list of additional variables to pass to "make" when running 
do_compile() and do_install(). I reduced it to bare minimum that cmem 
Makefiles require.

This is the default target for do_compile() function.

Again, just a cosmetic change.

Consolidate S assignment in one place.

One more cosmetic change.
