Brian Swetland 9c769f6931 [rp20xx][pico-sdk] add some missing / generated headers

- sys/cdefs is wanted for __CONCAT()
- version.h and config_autogen.h are generated by the pico sdk
- config_autogen expects to include board file
- instead define PICO_xyz in target rules.mk

LK

The LK embedded kernel. An SMP-aware kernel designed for small systems.

See https://github.com/littlekernel/lk for the latest version.

See https://github.com/littlekernel/lk/wiki for documentation.

Builds

To build and test for ARM on linux

install or build qemu. v2.4 and above is recommended.
install gcc for embedded arm (see note 1)
run scripts/do-qemuarm (from the lk directory)
you should see 'welcome to lk/MP'

This will get you a interactive prompt into LK which is running in qemu arm machine 'virt' emulation. type 'help' for commands.

note 1: for ubuntu: sudo apt-get install gcc-arm-none-eabi or fetch a prebuilt toolchain from http://newos.org/toolchains/arm-eabi-5.3.0-Linux-x86_64.tar.xz
