libbpf: Fix build with latest gcc/binutils with LTO
After updating to binutils 2.35, the build began to fail with an
assembler error. A bug was opened on the Red Hat Bugzilla a few days
later for the same issue.
Work around the problem by using the new `symver` attribute (introduced
in GCC 10) as needed instead of assembler directives.
This addresses Red Hat ([0]) and OpenSUSE ([1]) bug reports, as well as libbpf
issue ([2]).
