Subject: [PATCH AUTOSEL for 4.14 019/161] libbpf: Makefile set specified
 permission mode

From: Jesper Dangaard Brouer <brouer@...hat.com>

[ Upstream commit 7110d80d53f472956420cd05a6297f49b558b674 ]

The third parameter to do_install was not used by $(INSTALL) command.
Fix this by only setting the -m option when the third parameter is supplied.

The use of a third parameter was introduced in commit  eb54e522a000 ("bpf:
install libbpf headers on 'make install'").

Without this change, the header files are install as executables files (755).

Fixes: eb54e522a000 ("bpf: install libbpf headers on 'make install'")
