There are no longer any source files in the root dir, allowing us to remove the 'rm *.o *.a .*.d' from this top-level makefile. arch_clean doesn't remove lib/.*.d.

Don't shoot the file-mover :-) I didn't write it, but it looks like it's referring to how testdev (as opposed to pc-testdev) works, i.e. '-device testdev,chardev=testlog -chardev file,id=testlog,path=msr.out' > > +# As it happens, config.mak is valid shell script code, too :-) > > +source config.mak > > is this a well-established method of doing things or a hack?
