From: "Naveen N. Rao" <naveen.n.rao@xxxxxxxxxxxxxxxxxx>

[ Upstream commit cb0cc635c7a9fa8a3a0f75d4d896721819c63add ]

Selecting CONFIG_DEBUG_INFO_BTF results in the below warning from ld:
ld: warning: orphan section `.BTF' from `.btf.vmlinux.bin.o' being placed in section `.BTF'

Include .BTF section in vmlinux explicitly to fix the same.
