treewide: add ORIG_PATH variable 
Add a variable that stores the original value of $PATH
in the host system's shell, before Make alters it.

This can be useful for when it is necessary
to ignore symlinks and programs made by the build system.

Define this new variable before all instances of
'export PATH:=' or similar.

Available Commands:
help: This help text
info: Show a list of available target profiles
clean: Remove images and temporary build files
image: Build an image (see below for more information).
manifest: Show all package that will be installed into the image
package_whatdepends: Show which packages have a dependency on this
package_depends: Show installation dependency of the package
image:
By default 'make image' will create an image with the default
target profile and package set. You can use the following parameters
to change that:
make image PROFILE="<profilename>" # override the default target profile
make image PACKAGES="<pkg1> [<pkg2> [<pkg3> ...]]" # include extra packages
make image FILES="<path>" # include extra files from <path>
make image BIN_DIR="<path>" # alternative output directory for the images
make image EXTRA_IMAGE_NAME="<string>" # Add this to the output image filename (sanitized)
make image DISABLED_SERVICES="<svc1> [<svc2> [<svc3> ..]]" # Which services in /etc/init.d/ should be disabled
make image ADD_LOCAL_KEY=1 # store locally generated signing key in built images
make image ROOTFS_PARTSIZE="<size>" # override the default rootfs partition size in MegaBytes
manifest:
List "all" packages which get installed into the image.
You can use the following parameters:
make manifest PROFILE="<profilename>" # override the default target profile
make manifest PACKAGES="<pkg1> [<pkg2> [<pkg3> ...]]" # include extra packages
make manifest STRIP_ABI=1 # remove ABI version from printed package names
package_whatdepends:
List "all" packages that have a dependency on this package
You can use the following parameters:
make package_whatdepends PACKAGE="<pkg>"
package_depends:
List "all" packages dependency of the package
You can use the following parameters:
make package_depends PACKAGE="<pkg>"
