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]).
