4.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jesper Dangaard Brouer <brouer@xxxxxxxxxx>
[ 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'")
