I was wrong. `/usr/bin/perf` is just a shell script calling a kernel specific version. 
The real executable is in `linux-hwe-tools-4.**`. 
I checked the source of `linux-hwe-tools-4.15.0-36` and it already has the necessary fix. 
Rebuilding just the perf executable from withhin the source dir resulted in a binary with correct demangling support. 
```
apt-get source linux-hwe-tools-4.15.0-36
sudo apt-get build-dep linux-hwe-tools-4.15.0-36
cd linux-hwe-4.15.0/tools/perf && make 
```

However rebuilding and installing the package `linux-hwe-tools-4.15.0-36` resulted in a different binary with still broken demangling. I don’t know what’s the reason for that. 
```
apt-get source linux-hwe-tools-4.15.0-36
sudo apt-get build-dep linux-hwe-tools-4.15.0-36
cd linux-hwe-4.15.0 && debuild -us -uc -b
sudo dpkg -i ../linux-hwe-tools-4.15.0-36_4.15.0-36.39~16.04.1_amd64.deb ../linux-tools-4.15.0-36-generic_4.15.0-36.39~16.04.1_amd64.deb
```

Bug description:
  Hi,
  It appears that C++ demangling support is missing from linux-tools-3.16.0-24, on Utopic on arm64.

  Could the following please be added to the build dependencies for that package:
  libiberty-dev
  binutils-dev

  Installing the above and rebuilding the package fixed the problem for
  me.

  Cheers,
  --
  Steve
