[ Upstream commit 74d3320f6f7cf72de88a7e8df573821f6db90239 ]
When CONFIG_DEBUG_INFO_BTF_MODULES=y, running 'make modules' in the clean kernel tree will get the following error.
$ grep CONFIG_DEBUG_INFO_BTF_MODULES .config CONFIG_DEBUG_INFO_BTF_MODULES=y $ make -s clean $ make modules [snip] AR vmlinux.a ar: ./built-in.a: No such file or directory make: *** [Makefile:1241: vmlinux.a] Error 1
'modules' depends on 'vmlinux', but builtin objects are not built.
Define KBUILD_BUILTIN.
