# Given an array of dependencies and a block for retrieving dependencies of an
# dependency, returns an array of dependencies with three guarantees:
#
# 1) Contains all the listed dependencies.
# 2) Has no duplicates.
# 3) For any dependency in the list, all of its dependencies appear before it.
#
# Guarantee 3 only holds if the underlying graph has no circul dependencies.  If
# there is a circular dependency, it will not be detected, but it will not cause
# an infinite loop either.

WTF, I did something that affected the architecture of my cross-built ELF files?
