hi ：
My env is centos 7 . cmake 3.4 gcc 10.2 . i want to install dwarves. so i do as following:
1: git clone https://github.com/acmel/dwarves.git
2: make & make install
3: i build linux-5.15.46
There is wrong message :
pahole: symbol lookup error: pahole: undefined symbol: tabs
FAILED: load BTF from vmlinux: No such file or directory

In fact ,i want to build bpftool .
Thanks
