Maciek Borzecki 7a4ec93885 perf tools: Allow user to indicate path to objdump in command line
When analyzing perf data from hosts of other architecture than one of
the local host it's useful to call objdump that is part of a toolchain
for that architecture. Instead of calling regular objdump, call one that
user specified in command line.

perf-annotate(1)
================
NAME
----
perf-annotate - Read perf.data (created by perf record) and display annotated code
SYNOPSIS
--------
[verse]
'perf annotate' [-i <file> | --input=file] [symbol_name]
DESCRIPTION
-----------
This command reads the input file and displays an annotated version of the
code. If the object file has debug symbols then the source code will be
displayed alongside assembly code.
If there is no debug info in the object, then annotated assembly is displayed.
OPTIONS
-------
-i::
--input=::
Input file name. (default: perf.data unless stdin is a fifo)
-d::
--dsos=<dso[,dso...]>::
Only consider symbols in these dsos.
-s::
--symbol=<symbol>::
Symbol to annotate.
-f::
--force::
Don't complain, do it.
-v::
--verbose::
Be more verbose. (Show symbol address, etc)
-D::
--dump-raw-trace::
Dump raw trace in ASCII.
-k::
--vmlinux=<file>::
vmlinux pathname.
-m::
--modules::
Load module symbols. WARNING: use only with -k and LIVE kernel.
-l::
--print-line::
Print matching source lines (may be slow).
-P::
--full-paths::
Don't shorten the displayed pathnames.
--stdio:: Use the stdio interface.
--tui:: Use the TUI interface Use of --tui requires a tty, if one is not
present, as when piping to other commands, the stdio interface is
used. This interfaces starts by centering on the line with more
samples, TAB/UNTAB cycles through the lines with more samples.
-C::
--cpu:: Only report samples for the list of CPUs provided. Multiple CPUs can
be provided as a comma-separated list with no space: 0,1. Ranges of
CPUs are specified with -: 0-2. Default is to report samples on all
CPUs.
--asm-raw::
Show raw instruction encoding of assembly instructions.
--source::
Interleave source code with assembly code. Enabled by default,
disable with --no-source.
--symfs=<directory>::
Look for files with symbols relative to this directory.
-M::
--disassembler-style=:: Set disassembler style for objdump.
--objdump=<path>::
Path to objdump binary.
