Colin Cross a4447e8c89 Don't add dependencies on Makefiles when using ninja
Ninja has an implicit dependency on the command being run, and kati will
regenerate the ninja manifest if any read makefile changes, so there is no
need to have dependencies on makefiles.
This won't catch all the cases where LOCAL_ADDITIONAL_DEPENDENCIES contains
a .mk file, because a few users of LOCAL_ADDITIONAL_DEPENDENCIES don't
include base_rules.mk, but it will fix the most common ones.

# include this makefile to create the LOCAL_MODULE symlink to the primary version binary.
# but this requires the primary version name specified via LOCAL_MODULE_STEM_32 or LOCAL_MODULE_STEM_64,
# and different with the LOCAL_MODULE value

# Note: now only limited to the binaries that will be installed under system/bin directory
# Create link to the one used depending on the target
# configuration. Note that we require the TARGET_IS_64_BIT
