Patch: Support for grub at installation time

Hi folks,

Below you can find a tiny patch to add 2 new targets to the top level 
Makefile: bzgrub and zgrub. This is a suggestion about how the Grub 
boot loader could be supported.

It would be nice if you could consider this patch to be included in 
one of the future kernels. I am not the kernel patch specialist, so 
please excuse if I missed to follow a specific procedure.


Regards

Harri
