perf tools: Disable BPF skeleton if no libopenssl found
The libopenssl is required by bpftool which is needed to generate BPF
skeleton. Disable it by setting BUILD_BPF_SKEL to 0 otherwise it'll see
build errors like below:
CC /build/util/bpf_skel/.tmp/bootstrap/sign.o
sign.c:16:10: fatal error: openssl/opensslv.h: No such file or directory
16 | #include <openssl/opensslv.h>
| ^~~~~~~~~~~~~~~~~~~~
compilation terminated.
make[3]: *** [Makefile:256: /build/util/bpf_skel/.tmp/bootstrap/sign.o] Error 1
make[3]: *** Waiting for unfinished jobs....
make[2]: *** [Makefile.perf:1211: /build/util/bpf_skel/.tmp/bootstrap/bpftool] Error 2
make[1]: *** [Makefile.perf:287: sub-make] Error 2
make: *** [Makefile:76: all] Error 2
Now it'll skip the build with the following message:
Makefile.config:729: Warning: Disabled BPF skeletons as libopenssl is required
