#
# Generic Targets
#
# The following is a set of generic targets used across the makefile. The
# following targets are defined:
#
#     help
#         This target prints all supported targets. This is also the default
#         target.
#
#     $(BUILDDIR)/
#     $(BUILDDIR)/%/
#         This target simply creates the specified directory. It is limited to
#         the build-dir as a safety measure. Note that this requires you to use
#         a trailing slash after the directory to not mix it up with regular
#         files. Lastly, you mostly want this as order-only dependency, since
#         timestamps on directories do not affect their content.
