parisc: make "make install" not depend on vmlinux
Install targets (install, zinstall, uinstall) on parisc have a dependency to vmlinux. This may cause parts of the kernel to be rebuilt during installation. We must avoid this since this may run as root. Install targets "ABSOLUTELY MUST NOT MODIFY THE SOURCE TREE." as Linus emphasized this in: http://lkml.org/lkml/2013/7/10/600 So on parisc and maybe other archs we need the same as for x86: 1648e4f8 x86, kbuild: make "make install" not depend on vmlinux This parisc patch was inspired by: 19514fc6 arm, kbuild: make "make install" not depend on vmlinux Signed-off-by: Helge Deller <deller@gmx.de>
