For embedded platforms, we want to be able to build the perf
tools on a build machine to run on a different arch. This patch
allows $CROSS_COMPILE to set the cross compiler.
Additionally, if NO_LIBPERL is set, then don't use perl include
paths as they will be for the host arch.

When we have a maximum latency reported for a task, we need a
convenient way to find the matching location to the raw traces
or to perf sched map that shows where the task has been
eventually scheduled in. This gives a pointer to retrieve the
events that occured during this max latency.

In current code, task's execute time is got by reading
'/proc/<pid>/sched' file, it's wrong if the task is created
by pthread_create(), because every thread task has same pid.
This way also has two demerits:
1: 'perf sched replay' can't work if the kernel is not
compiled with the 'CONFIG_SCHED_DEBUG' option
2: perf tool should depend on proc file system
So, this patch uses PERF_COUNT_SW_TASK_CLOCK to get task's
execution time instead of reading /proc file.
Changelog v2 -> v3:
use PERF_COUNT_SW_TASK_CLOCK instead of rusage() as Ingo's
suggestion

Fix add-probe command syntax without --add option.
perf-probe supports add-probe command without --add
option. But it treats each argument as an event definition.
e.g.
perf probe func arg1 arg2
is interpreted as
perf probe --add func --add arg1 --add arg2
But it may be useless in many cases.
This patch fixes this syntax to fold those arguments into
one event definition if there is no --add option. With this
change, above command is interpreted as below;
perf probe --add "func arg1 arg2"

Uses of strcat are almost always signs that someone is too lazy
to think about the code a bit more carefully. One always has to
know about the lengths of the strings involved to avoid buffer
overflows.
This is one case where the size of the object code for me is
reduced by 38 bytes. The code should also be faster, especially
if flags is non-NULL.

So, this use "zero_buf" to write aligned area.
- util/trace-event-read.c

Currently, sample event data is parsed for each commands, and it
is assuming that the data is not including other data. (E.g.
timechart, trace, etc. can't parse the event if it has
PERF_SAMPLE_CALLCHAIN)
So, even if we record the superset data for multiple commands at
a time, commands can't parse. etc.
To fix it, this makes common sample event parser, and use it to
parse sample event correctly. (PERF_SAMPLE_READ is unsupported
for now though, it seems to be not using.)

Add probe-finder.h as LIB_H without libdwarf, because that
header is included even if no libdwarf.

Change annoying debug-info using notice from pr_info() to
pr_debug(), since the message always printed when user adds a
probe point which requires debug-info.

Fedora needs perl-ExtUtils-Embed for Perl scripting, which also
brings along libperl-devel; note this info for the convenience
of Fedora users.

The common_* functions (e.g. common_pc(), etc) are exported as
common_* but named get_common_*, resulting in unresolved
subroutine errors when executing scripts.
Make the internal and external names match.

The debugging versions of the ENTER and LEAVE internal perl
macros, used when embedding perl, define a local block with a
my_perl perl variable that shadows a global variable of the same
name, which is also the name expected by the embedding API for
the embedded interpreter.
Since we don't have control over the code generated in this case
(it's an externality) and can't get rid of the warning, ignore it.

The backtick shell substitutions for PERL_EMBED_LDOPT/CCOPT make
a lot of noise on stderr if Embed.pm isn't installed - this
silences them.
