Casual building in the tree leads to regular messups where I forget to
clean up the outdir first when switching platforms and the build fails
in strange ways.
Put a $(BOARD) subdirectory under outdir, and use that at $(O) when
the user does not provide an output directory.
Note that "make pristine" continues to remove the entire outdir,
including other architecutres (so as to make the tree pristine).
Also update a few spots where outdir was mentioned in documentation to
clarify the new scheme.

On galileo, UART_0 IRQ is incorrectly mapped to IRQ 0
UART_0 IRQ should be mapped to IRQ 17 (same as UART_1 IRQ)
but NS16550 driver doesn't support mapping same IRQ for
different devices.
This is creating crashes when dumping profiler data on UART
CONSOLE (UART_1) with UART console enabled (UART in interrupt
mode)
This patch is disabling UART_0 in sample apps and adding a note
in the README file
This problem appeared due to following commit:
e643cede3a uart: add ISR callback mechanism for UART drivers
Since that commit, UART driver is setting the ISR for all
UART device instances when interrupt mode is enabled

On Quark SE, using system timer as event timestamp creates
inconsistencies since the timer is handled by software in
timer_int_handler and tickless_idle_exit. So timestamp does not
reflect timing of certain events like timer IRQ.
This patch introduces the usage of RTC or AON counter as kernel
event logger timestamp

This patches includes
- a profiler file/Makefile that can be added to an application to enable
kernel event logger flush over UART
- a nanokernel and a microkernel sample application permitting to
exercise the profiler
- scripts permitting to get kernel event profiler data over UART
console and post-process this data
