From: Thomas Weißschuh Date: Thu, 13 Feb 2025 14:55:17 +0000 (+0100) Subject: kbuild: userprogs: fix bitsize and target detection on clang X-Git-Tag: v6.14-rc3~1^2~1 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=1b71c2fb04e7;p=thirdparty%2Fkernel%2Flinux.git kbuild: userprogs: fix bitsize and target detection on clang scripts/Makefile.clang was changed in the linked commit to move --target from KBUILD_CFLAGS to KBUILD_CPPFLAGS, as that generally has a broader scope. However that variable is not inspected by the userprogs logic, breaking cross compilation on clang. Use both variables to detect bitsize and target arguments for userprogs.
