From e4a42c82e943b97ce124539fcd7a47445b43fa0d Mon Sep 17 00:00:00 2001 From: Denis Efremov Date: Mon, 8 Jun 2020 12:59:44 +0300 Subject: [PATCH] kbuild: fix broken builds because of GZIP,BZIP2,LZOP variables Redefine GZIP, BZIP2, LZOP variables as KGZIP, KBZIP2, KLZOP resp. GZIP, BZIP2, LZOP env variables are reserved by the tools. The original attempt to redefine them internally doesn't work in makefiles/scripts intercall scenarios, e.g., "make GZIP=gzip bindeb-pkg" and results in broken builds. There can be other broken build commands because of this, so the universal solution is to use non-reserved env variables for the compression tools.
