[PATCH AUTOSEL 5.4 23/26] kbuild/deb-pkg: annotate libelf-dev dependency as :native

From: Sasha Levin
Date: Fri Jan 10 2020 - 17:08:14 EST


From: Ard Biesheuvel <ardb@xxxxxxxxxx>

[ Upstream commit 8ffdc54b6f4cd718a45802e645bb853e3a46a078 ]

Cross compiling the x86 kernel on a non-x86 build machine produces
the following error when CONFIG_UNWINDER_ORC is enabled, regardless
of whether libelf-dev is installed or not.

dpkg-checkbuilddeps: error: Unmet build dependencies: libelf-dev
dpkg-buildpackage: warning: build dependencies/conflicts unsatisfied; aborting
dpkg-buildpackage: warning: (Use -d flag to override.)

Since this is a build time dependency for a build tool, we need to
depend on the native version of libelf-dev so add the appropriate
annotation.
