From: Harish Sadineni <[email protected]>

Enabling the Rust in-kernel feature pulls in clang-native as a
dependency for the kernel build. During the perf build, the presence of clang
causes all BUILD_BPF_SKEL dependency checks to succeed, which makes perf attempt
to build bpftool as part of its build process and make build to fail.

Previously, When Rust support was not enabled, BUILD_BPF_SKEL is set 0 due to 
missing
clang dependency.

Error:
| make[3]: *** ../bpf/bpftool: No such file or directory.  Stop.

As a workaround currently disabling BUILD_BPF_SKEL to make perf to build.
