make: Substitute build root with placeholder in defines

Reduce the space taken by some module_config.h variables
by substituting the full build root path with the
__BUILDROOT__ placeholder. E.g. this reduces the size
of MODULE_SRCDEPS for binderRpcTest from 70K to 48K.

Builds

Build Status

To build and test for ARM on linux

  1. install or build qemu. v2.4 and above is recommended.
  2. install gcc for embedded arm (see note 1)
  3. run scripts/do-qemuarm (from the lk directory)
  4. 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
