# Parallel execution of this Makefile is disabled because it changes
# the packages building order, that can be a problem for two reasons:
# - If a package has an unspecified optional dependency and that
# dependency is present when the package is built, it is used,
# otherwise it isn't (but compilation happily proceeds) so the end
# result will differ if the order is swapped due to parallel
# building.
# - Also changing the building order can be a problem if two packages
# manipulate the same file in the target directory.
#
# Taking into account the above considerations, if you still want to execute
# this top-level Makefile in parallel comment the ".NOTPARALLEL" line and
