Subject: libbpf: Compile in PIC mode only for shared library case
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=b0efc216f577997bf563d76d51673ed79c3d5f71;p=linux.git

libbpf: Compile in PIC mode only for shared library case

Libbpf compiles .o's for static and shared library modes separately, so no
need to specify -fPIC for both. Keep it only for shared library mode.
