Linux Kconfig creates a header file for each Kconfig symbol that
changed in between build runs and re-configurations. This feature

Only pentium4 was tested with the default sanity_chk, since it was
listed as the default platform on every test.
The ARM platforms were already taking a different approach: if the test
is runnable, build and run it for the QEMU platform (ti_lm3s6965):
otherwise, build it for the real board (fsl_frdm_k64f), since running on
that board is not currently automated.
Do something similar for x86 platforms: when runnable, use either
pentium4 or minuteia on QEMU; this gives coverage to minuteia. Also, for
a couple of build-only tests, build one for quark and one for atom.

The nanokernel LIFOs could only have one fiber pending on one of
them concurrently. If a second fiber wanted to take a contested
LIFO, if would kick the pending fiber out of the wait 'container',
but would not put it in back in the ready queue with an error. Instead,
it would, for all intents and purposes, remove it from the scheduling
mechanism of the nanokernel: the fiber would be 'lost' at that point.
The nanokernel LIFOs now make use of the fiber pend queue, and thus
allow multiple fibers to pend concurrently.
sysgen is updated since the microkernel initializes statically two
LIFOs, one for the command packets and one for the timer packets, and
the LIFO data structure has changed.
The nano_timers use the LIFOs and look at their internals, so they are
updated as well.
