[PATCH 1/2] kbuild: Fix link to headers in 'make deb-pkg'

[Joerg Roedel]

The Link to the kernel header files in the debian packages
point to the original build directory. This is a bad choice
if the packages were installed on a different machine. Fix
this in by manually re-creating the link in the builddeb
script.

[PATCH 2/2] kbuild: Only build linux-image package for UML

[Joerg Roedel]

For user-mode Linux the other packages are not required. So
only build the package with the linux-image in it.

But I've never touched UML either so we should get confirmation that
this really is the right thing to do.

there is a wishlist bug opened ages ago (and pinged not so long ago)
requesting headers to be packaged in debian:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=186930
Just to say that there is some interest in having headers packaged
somehow.

As there was no further reaction, I applied the patch now to
kbuild.git#misc.
