tools/perf/build: Pass through DEBUG parameter

Arnaldo reported that 'make DEBUG=1' does not work anymore.

The reason is that 'Makefile' only passes it through to
'Makefile.perf' via the environment, but 'Makefile.perf'
checks that it's a command line option:

    ifeq ("$(origin DEBUG)", "command line")
      PERF_DEBUG = $(DEBUG)
    endif

So pass it through properly, and also clean up DEBUG parameter
handling while at it and fix a couple of annoyances:

 - DEBUG=0 used to be interpreted as 'debugging on'. Turn it
   into 'debugging off' instead.

 - Same was the case for 'DEBUG=' - turn that into debug-off
   as well.

 - Pass in just a clean, sanitized 'DEBUG' value and get rid of

tools: Harmonize the various build messages in perf, lib-traceevent, lib-lk

    CC builtin-buildid-list.o
    CC builtin-buildid-cache.o

  BUILD STATIC LIB   libtraceevent.a
    CC builtin-probe.o
    CC builtin-kmem.o

perf evlist: Fix perf_evlist__mmap_read event overflow

The perf_evlist__mmap_read used 'union perf_event' as a placeholder for
event crossing the mmap boundary.

This is ok for sample shorter than ~PATH_MAX. However we could grow up
to the maximum sample size which is 16 bits max.

I hit this overflow issue when using 'perf top -G dwarf' which produces
sample with the size around 8192 bytes.  We could configure any valid
sample size here using: '-G dwarf,size'.

Using array with sample max size instead for the event placeholder. Also
adding another safe check for the dynamic size of the user stack.

TODO: The 'struct perf_mmap' is quite big now, maybe we could use some
lazy allocation for event_copy size.

perf bench: Fix failing assertions in numa bench

Patch adds more subtle handling of -C and -N parameters in
parse_{cpu,node}_setup_list() functions when there isn't enough NUMA
nodes or CPUs present.  Instead of assertion and terminating benchmark,
partial test is skipped with error message and perf will continue to the

perf tools: Fix srcline sort key behavior

Currently the srcline sort key compares ip rather than srcline info.  I
guess this was due to a performance reason to run external addr2line
utility.  Now we have implemented the functionality inside, use the
srcline info when comparing hist entries.

Also constantly print "??:0" string for unknown srcline rather than
printing ip.

When the srcline sort key is used , the external addr2line utility needs
to be run for each hist entry to get the srcline info.  This can consume
quite a time if one has a huge perf.data file.

So rather than executing the external utility, implement it internally

This is just for the low hanging fruit 'cmd' arg, a proper beautifier
