8297348: make CONF=xxx should match if xxx is an exact match

[magicus]

A typical use case for multiple configurations is that you have a release configuration (say linux-x64) and a debug configuration (say linux-x64-debug). You can now easily select the debug configuration with CONF=debug, or both configurations with CONF=, but there is no way to select just the release configuration. Instead, workarounds using SPEC or CONF_NAME (which always does an exact match) is needed.

Instead, we should modify the behavior of CONF slightly, so if it gets an exact match, it should behave like CONF_NAME and select just that configurations.
