Bugs in this:
- it breaks kernxref.sh some more for elf kernels. LKMs always have a.out
format, but the kernel may have elf format. kernxref.sh should look at
modules instead of LKMs, but since modules are in the default format,
that will only work when the kernel is in the default format.
- it makes a line longer than 80 characters.
