kerneltags and kernelconfig are phony targets, so mark them
with .PHONY.

ANDROID_BUILD_TOP variable is deprecated and thus all paths are assumed
to be relative to the top directory. However, this is causing problem
when some of the paths are constructed in the Android build system and
used in the non-Android makefiles that are usually executed NOT at the
top directory but at a sub directory using -C option. As a result, the
relative path from the Android build system become invalid in the
non-Android makefiles.
In order to overcome the restriction, ANDROID_BUILD_TOP is manually
constructed when invoking the non-Android makefiles by using $$(pwd).
The non-Android makefiles are expected to construct the absolute path
by prepending ANDROID_BUILD_TOP to any path that came from the Android
build system.

The dtb.img is made by concatenating all the compiled dtbs
after the kernel is compiled. This dtb.img is then added to be
a part of the boot.img.

Add support to configure DLKM install path.
TARGET_OUT is hard coded to system directory.
Use PRODUCT_OUT instead of TARGET_OUT to use user configured path
instead.

Add support to pass build flags while compiling Linux kernel.
This change is required to add support in Linux kernel to use external
host executable. (example: dtc)
Usage example:
TARGET_KERNEL_MAKE_ENV := DTC_EXT=dtc$(HOST_EXECUTABLE_SUFFIX)

Fixes 2 problems related to multi-kernel tree support:
1. Copying of modules to /system/lib/modules is broken when building
in a multi-kernel tree. This is because INSTALL_MOD_PATH is not
set correctly. When building a multi-kernel tree, the output
directory is one additional directory deep, so modules end up
under <out>/obj/system/lib/modules instead of
<out>/system/lib/modules. Fix this by using BUILD_ROOT_LOC
which is set appropriately for multi-kernel and standard trees.
2. When running "make kernelconfig" on a multi-kernel tree,
the generated defconfig is copied to the wrong location,
since it uses the old-style location under kernel, instead
of kernel/<kernel name>.

Always create the KERNEL_OBJ symlink for legacy reference
support when using the new directory style. Earlier the
generation relies on another make target that requires it.
Also solve a minor issue where the make @(hide) was incorrectly
used within a shell command.

We now support building Android in a build tree that contains
multiple kernels. The kernel version to be built is passed in
by the higher level makefiles.
Currently supported structure:
- legacy <Android Root>/kernel
- New <Android Root>/kernel/msm-*
