Arnaldo Carvalho de Melo b0618f38e2 perf build: Gracefully fail the build if BUILD_BPF_SKEL=1 is specified and clang isn't available 
Build BPF skels require having a compiler able to generate BPF bytecode,
and so far this is only possible with clang, so check for its
availability and fail the build when the user explicitely ask for BPF
skels to be built.
