From 60fb0b1239719df2ec92606fa037f7c116810762 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Wed, 29 Apr 2020 12:45:23 +0900 Subject: samples: pidfd: build sample program for target architecture This userspace program includes UAPI headers exported to usr/include/. 'make headers' always works for the target architecture (i.e. the same architecture as the kernel), so the sample program should be built for the target as well. Kbuild now supports 'userprogs' for that. I also guarded the CONFIG option by 'depends on CC_CAN_LINK' because $(CC) may not provide libc.
