[make] add feature to allow multiple parallel build dirs
...
Using environment variables LKROOT and LKINC you can specify multiple
parallel top level directories (outside of the lk root) that are overlayed
on top of the build system. This allows for a structure like
lk/
testproject/
someotherfirmware/
Where each of these subdirs has an entire overlayed tree of libraries, platforms,
targets, and projects.
To accomplish this, copy makefile into the root dir and build a lk_inc.mk that
sets LKROOT and LKINC.

[make] better modularize the build system
...
-Each module's rules.mk defines a seperate linkage unit. Each
module can have a private set of CFLAGS, DEFINES, INCLUDES, and so
forth.
-Files to be compiled are now added by source, not object.
Most rules.mk files can be converted easily by following these steps:
1) add 'MODULE := $(LOCAL_DIR)' near the top of the file
2) change OBJS += to MODULE_SRCS += and list source files instead of .os
3) add 'include make/module.mk' at the bottom of the file
See make/module.mk for directions.
