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: Shared Floating Point Support

Description:

This test uses two tasks to independently compute pi, while two other tasks
load and store floating point registers and check for corruption. This tests
the ability of tasks to safely share floating point hardware resources, even
when switching occurs preemptively. (Note that both sets of tests run
concurrently even though they report their progress at different times.)

The demonstration utilizes microkernel mutex APIs, timers, semaphores,
round robin scheduling, and floating point support.

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
