Anas Nashif 60b18711f3 tests: remove duplicate kernel configs and usage of ARCH Many test configs are the same, remove complexity and duplication by using just one kernel config where applicable. This removes the usage of ARCH which is a remnant from the days where we had to specify the architecture of the board, the architecture is now part of Kconfig and determined basded on the board configuration. This will also make it easy adding new architectures to test cases without having to add an architecture specific config file when it is actually not needed, for example now that we will enable micro-kernel support on ARC.

Title: Kernel Event Logger Sample

Description:

This sample uses the philosopher sample with two additional tasks to show the
profiling data on different system's states. The fork manager task controls the
fork's availibilty. The worker task performs intermitently heavy processing,
allowing or preventing the system to go idle.

--------------------------------------------------------------------------------

Building and Running Project:

This microkernel project outputs to the console. It can be built and executed
on QEMU as follows:

    make qemu

--------------------------------------------------------------------------------

Troubleshooting:

Problems caused by out-dated project information can be addressed by
issuing one of the following commands then rebuilding the project:

    make clean          # discard results of previous builds
                        # but keep existing configuration info
or
    make pristine       # discard results of previous builds
                        # and restore pre-defined configuration info


Problems with QEMU on ARM:
Qemu v2.1 for ARM platform do not support tickless idle. If run the sample
project in QEMU with the CONFIG_TICKLESS_IDLE option enabled, the project
could present an erratic behaviour.
