Description of the bug:

When a configuration transition depends on a user-defined flag, the transition doesn't update when the flag's default value updates.

This produces incorrect output for incremental builds (build a target, change the flag default, build the target again).

Workarounds:

• Force re-analysis by arbitrarily changing some other flag at the command line
• bazel shutdown to clear the transition cache

What's the simplest, easiest way to reproduce this bug? Please provide a minimal example if possible.
