Bug#961299: Acknowledgement (FTBFS: debhelper compatibility level 12 breaks linux kernel build on hppa/parisc)

[Helge Deller <deller@gmx.de>]

It turns out, that changing
	dh_strip --no-automatic-dbgsym -Xvmlinux
to
	dh_strip --no-automatic-dbgsym -Xvmlinux -Xvmlinuz
in debian/rules.real fixes the build.

I added some tracing code and this shows that in former compat level 9,
the strip command is never executed on the vmlinuz file, while with
compat level 12, strip is now executed like this and thus fails:

        strip --remove-section=.comment --remove-section=.note --strip-unneeded debian/linux-image-5.6.0-1-parisc64/boot/vmlinuz-5.6.0-1-parisc64
strip: debian/linux-image-5.6.0-1-parisc64/boot/vmlinuz-5.6.0-1-parisc64: file format not recognized
dh_strip: error: strip --remove-section=.comment --remove-section=.note --strip-unneeded debian/linux-image-5.6.0-1-parisc64/boot/vmlinuz-5.6.0-1-parisc64 returned exit code 1

Any chance we can add "-Xvmlinuz" to the dh_strip command in rules.real?
