# Include this makefile to create the LOCAL_MODULE symlink to the primary version binary.
# Include this file only after "include $(BUILD_EXECUTABLE)".
# It requires the primary version name specified via LOCAL_MODULE_STEM_32 or LOCAL_MODULE_STEM_64,
# and different from 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
# check because 32 bit targets may not define TARGET_PREFER_32_BIT_APPS
# et al. since those variables make no sense in that context.
