perf build: Fix error message when asking for -fsanitize=address without required libraries (2020-06-18 10:34:31 -0300)

----------------------------------------------------------------
perf tooling fixes for v5.8:

- Update various UAPI headers, some automatically adding support for a new MSR and the faccess2 syscall.

- Fix corner case NULL deref in the histograms code.

- Fix corner case NULL deref in 'perf stat' aggregation code.

- Fix array pointer deref and old style declaration in the parsing of events.

- Fix segfault when processing ZSTD compressed perf.data files in 'perf script' due to lack of initialization of the ZSTD library.

- Handle __attribute__((user)) in libtraceevent fixing the parsing of syscall tracepoints with user buffers.

- Make libtraevent aware of __builtin_expect() appearing in tracepoint fields.

- Make the BPF prologue generation use bpf_probe_read_{user,kernel}().

- Fix the '@user' attribute parsing in kprobes variables in 'perf probe'.

- Fix error message when asking for -fsanitize=address without required libraries.
