Actually, yes and now. The stripping will go back into per-package, but
inside the package infrastructure instead. This is because we want to
do all the cleanup (documentation, headers, useless .a and .la files)
right after the package installation in order to make the "package
management" stuff work (this is something that Lionel already did in
his experiments of package management). So it will not be inside each
package .mk file as it used to be, but it's still going to be done on a

In this particular case, the stripping is very much kernel-specific, so
I don't see a strong reason of adding this to linux/linux.mk. Except
maybe packages that do compile additional kernel modules, such as
linux-fusion (and more could be added).
