perf does not build with:

libbpf.c: In function 'bpf_object__close':
libbpf.c:4205:15: error: 'struct bpf_object' has no member named 
'btf_vmlinux'
   btf__free(obj->btf_vmlinux);
                ^~

due to 34d66b750e83d49c7d3d33d59e6a1b49e0d5db15 ("libbpf: Free 
btf_vmlinux when closing bpf_object")

the btf_vmlinux member was introduced with 
a6ed02cac690b635dbb938690e795812ce1e14ca ("libbpf: Load btf_vmlinux only 
once per object.") which is only in >= 5.6.

Suggset we drop that commit.
