Bug 994246 - Prevent librs_jni from building
Bug 1004195 - Add support for device tree in boot.img

Add support for optional device tree image (dt.img)
to boot and recovery images.  Some devices use kernel device
tree and this adds the device tree image as a section within
the boot/recovery images.

Bug 1004195: Handle bootable/recovery/res being a symlink.

Some versions of `bootable/recovery` replace the subdirectory `res` with
a symlink to a copy in `librecovery`, so that FxOS-specific graphics can
be used from the mozilla-b2g fork of that project.  However, this causes
`cp -rf` to try to copy the symlink itself (and fail), and `find` to not
resolve the symlink to find the actual dependencies.

The trailing slash added in this patch fixes these problems.
