I think, circular dependencies should (and must) be supported. It is
nearly impossible to avoid them and other package managers (rpm, dpkg)
work fine with them.

Forbidding them would require a large rewrite of oe recipes; e.g. the
autogenerated perl deps cause a circle leading to

| Installing perl-module-extutils-makemaker (5.14.2-r2) to root...
| Installing perl-module-extutils-my (5.14.2-r2) to root...
| Installing perl-module-extutils-mm (5.14.2-r2) to root...
| Installing perl-module-extutils-makemaker (5.14.2-r2) to root...
| Installing perl-module-extutils-my (5.14.2-r2) to root...
| Installing perl-module-extutils-mm (5.14.2-r2) to root...

loops.

afais, dpkg supports a 'Pre-Depends' field which breaks the dependency
circles.  rpm supports more finegrained 'Requires(preinst/postinst)'
tags too.
