I strongly disagree. LLVM (and all of its accompanying tools) need to build
in environments which do not support resolving cyclic depndencies at link
times. It is really important to structure and layer the libraries to avoid
cycles. This may mean fewer and more coarse grained libraries, but it's
important to take that approach rather than assume the availability of
facilities like --start-group/--end-group.
