These are pretty self-explainable. I think I tried to sumbit these
changes with the serial debugging patch year and some months ago and I
was told to sign the copyright assignment. I have already done that
now. :)

* kern/main.c (grub_main) [!GRUB_UTIL]: Alias grub_main to main,
so that gdb is able to find stack top.
* genmk.rb: replace strip with objcopy, so unstripped files are
left untouched for debugging purposes.
