tools/bpf: fix perf build error with uClibc (seen on ARC)
When build perf for ARC recently, there was a build failure due to lack
of __NR_bpf.
| Auto-detecting system features:
|
| ... get_cpuid: [ OFF ]
| ... bpf: [ on ]
|
| # error __NR_bpf not defined. libbpf does not support your arch.
^~~~~
| bpf.c: In function 'sys_bpf':
| bpf.c:66:17: error: '__NR_bpf' undeclared (first use in this function)
| return syscall(__NR_bpf, cmd, attr, size);
| ^~~~~~~~
| sys_bpf
