Subject: [PATCH 0/2] perf tools: Fix perf build with dynamic libbpf

hi,
sending fixes for building perf with LIBBPF_DYNAMIC=1.

We hit the window where perf uses libbpf functions, that did not
make it to the official libbpf release yet and it's breaking perf
build with dynamicly linked libbpf. Fixing this with adding weak
stub functions for possibly missing libbpf function.

thanks,
jirka
