If mtools.conf is not generated before, 'make isoimage' could complain:
Kernel: arch/x86/boot/bzImage is ready (#597)
GENIMAGE arch/x86/boot/image.iso
*** Missing file: arch/x86/boot/mtools.conf
arch/x86/boot/Makefile:144: recipe for target 'isoimage' failed
mtools.conf is not used for isoimage generation, so do not check it.
