kbuild, deb-pkg: support overriding userland architecture (55f88ecc) · Commits · 戴 / test

Usefull if building for sparc64 userland, because the sparc and sparc64 userlands use the same 64-bit kernel, making it impossible to always select the correct userland architecture for the resulting debian package. Might also be usefull, if you want a i386 userland with a amd64 kernel. Example usage: make KBUILD_DEBARCH=i386 deb-pkg LKML-reference: <alpine.DEB.2.02.1011051437500.13287@aurora.sdinet.de> Signed-off-by:

		KBUILD_DEBARCH
		--------------------------------------------------
		For the deb-pkg target, allows overriding the normal heuristics deployed by
		deb-pkg. Normally deb-pkg attempts to guess the right architecture based on
		the UTS_MACHINE variable, and on some architectures also the kernel config.
		The value of KBUILD_DEBARCH is assumed (not checked) to be a valid Debian
		architecture.

		ARCH
		--------------------------------------------------
		Set ARCH to the architecture to be built.
