 # Autotools package infrastructure
 #
 # This file implements an infrastructure that eases development of
 # package .mk files for autotools packages. It should be used for all
 # packages that use the autotools as their build system. Non-autotools
 # packages should use the generic infrastructure in
 # package/Makefile.package.in.
 #
 # See the Buildroot documentation for details on the usage of this
 # infrastructure
 #
 # In terms of implementation, this autotools infrastructure requires
 # the .mk file to only specify metadata informations about the
 # package: name, version, download URL, etc.
 #
 # We still allow the package .mk file to override what the different
 # steps are doing, if needed. For example, if <PKG>_BUILD_CMDS is
 # already defined, it is used as the list of commands to perform to
 # build the package, instead of the default autotools behaviour. The
 # package can also define some post operation hooks.

 # AUTOTARGETS_INNER -- defines how the configuration, compilation and
 # installation of an autotools package should be done, implements a
 # few hooks to tune the build process for autotools specifities and
 # calls the generic package infrastructure to generate the necessary
 # make targets
 #
 #  argument 1 is the lowercase package name
 #  argument 2 is the uppercase package name, including an HOST_ prefix
 #             for host packages
 #  argument 3 is the uppercase package name, without the HOST_ prefix
 #             for host packages
 #  argument 4 is the package directory prefix
 #  argument 5 is the type (target or host)
