[PATCH 1/1] kbuild: deb-pkg: Allow parallel build
From: Bastian Germann
Date: Mon Mar 13 2023 - 13:12:29 EST
Currently, the only way to build the deb-pkg generated package parallely
is adding -jN to the MAKEFLAGS environment variable. The package ignores
the usual parallel build option that is described in Debian Policy §4.9.1.
Derive make's -j parameter from the DEB_BUILD_OPTIONS environment variable
that ends up being set by Debian's build tools.
