# Link type checking
#
# ALL_LINK_TYPES contains a list of all link type prefixes (generally one per
# module, but APKs can "link" to both java and native code). The link type
# prefix consists of all the information needed by intermediates-dir-for:
#
#  LINK_TYPE:TARGET:_:2ND:STATIC_LIBRARIES:libfoo
#
#   1: LINK_TYPE literal
#   2: prefix
#     - TARGET
#     - HOST
#     - HOST_CROSS
#     - AUX-<variant-name>
#   3: Whether to use the common intermediates directory or not
#     - _
#     - COMMON
#   4: Whether it's the second arch or not
#     - _
#     - 2ND_
#   5: Module Class
#     - STATIC_LIBRARIES
#     - SHARED_LIBRARIES
#     - ...
#   6: Module Name
#
# Then fields under that are separated by a period and the field name:
#   - TYPE: the link types for this module
#   - MAKEFILE: Where this module was defined
#   - BUILT: The built module location
#   - DEPS: the link type prefixes for the module's dependencies
#   - ALLOWED: the link types to allow in this module's dependencies
#   - WARN: the link types to warn about in this module's dependencies
#
# All of the dependency link types not listed in ALLOWED or WARN will become
# errors.
