Fixes #define clash between profiling code and sudoku plugin

Fixes profile instrumentation function names to match what gcc expects (please can someone confirm on a non-cygwin build environment that this does indeed also work for them)

Fixes profiling code to pass required CPU/COP arg to timer_register() on devices with cop

Fixes profile_reader to execute the correct objdump executable (=> now passed on command line as new required argument - e.g. "profile_reader profile.out arm-elf-objdump ...")

Adds error message when no output sort order is specified (no order => no output! confusing to just get no output and no explanation why not)

Fixes sort order in profile_reader output (wasn't sorting numeric fields numerically before, or at least not correctly!)

Fixes linked list depth always being zero in output (column: "DEPTH" value always 0000 - recursive print code was recursing with depth++ rather than ++depth!!)

Then also some probably more contentious changes:
When profiling build is enabled, don't build alac.codec, doom, and mpegplayer. These cannot link on ipod video builds due to iram usage of profiling code
