[pkg-nvidia-devel] Bug#450653: nvidia-kernel-legacy-71xx-source: fails to build via make-kpkg (nested fakeroot)

[Michel Casabona]

Package: nvidia-kernel-legacy-71xx-source
Version: 71.86.01-1
Severity: important
Tags: patch

Hi,

The module fails to build using make-kpkg because debian/rules calls
itself "make" through fakeroot, which doesn't support nested calls.

The correct way to build "as root" is to use the --rootcmd option
of make-kpkg.

Note that dh_testroot would have stopped the build, if not run as
root or pseudo root by one mean or another, before the call to
make, so fakeroot here is useless.

The fix is simply to remove $(ROOT_CMD):
