Markus Mayer b2c043b29a package/linux-tools: change method for including linux-tool sub-makefiles
Make inclusion ordering of all linux-tool-*.mk sub-makefiles explicit
instead of relying on alphabetical sort order. This is done by
renaming the Linux tools sub-makefiles to the format linux-tool-*.mk.in.
This causes the top-level Makefile to ignore the Linux tools
sub-makefiles.

Until now, the main Makefile included all linux-tool-*.mk files, as
well as linux-tools.mk, and it relied on alphabetical sorting to
include them in the proper order (linux-tool-*.mk before
linux-tools.mk).

# Instead, we directly build in the sources of the linux package. We can do
# that, because we're not building in the same location and the same files.
#
# So, all tools refer to $(LINUX_DIR) instead of $(@D).
# Note: we need individual tools makefiles to be included *before* we build
# the list of build and install hooks below to guarantee that each tool has
# a chance to register itself once, and only once. Therefore, the makefiles
# are named linux-tool-*.mk.in, so they won't be picked up by the top-level
# Makefile, but can be included here, guaranteeing the single inclusion and
# the proper ordering.
