While we're at it, can we clean up the rule for .hdepend? Currently my
shell barfs when I evaluate the backticks (too many args). Though this
is probably something that will only happen to people who are cross
compiling kernels on another platform (in my case, an RS/6000 AIX3.2.5
box), it would be nice if we could fix this. I think the simple fix is
to use xargs. Anyone have a better idea? Below is a suggested patch.
I'll assume Ian's patch, but is it small enough that you will get the
idea regardless...
