Hi,
I'd like to build bpftool on alpine linux, which is musl based.
There are a few incompatibilities with it, I've commented on each patch
when I could think of alternative solutions.
I've tested the patch on an x86_64 debian testing with no problem, so
didn't obviously break glibc builds, and the binaries built for alpine
seem to work on aarch64 as well.
