Similar to commit 835a50753579 ("selftests/bpf: Add -fms-extensions to bpf build flags") and commit 639f58a0f480 ("bpftool: Fix build warnings due to MS extensions")
The kernel is now built with -fms-extensions, therefore generated vmlinux.h contains types like: struct slab { .. struct freelist_counters; };
Use -fms-extensions and -Wno-microsoft-anon-tag flags to build bpf programs that #include "vmlinux.h"
