If you look at https://wiki.linaro.org/Platform/Android/LinaroAndroidBuildService it has

"As explained above, you may use other options/variables as supported by Android makefiles (they will be exported to the environment)."

I.e. it's explicitly documented that *arbitrary* variables can be used in android-build.linaro.org , it's just the case that some of variables have well-defined semantics (as documented in https://wiki.linaro.org/Platform/Android/LinaroAndroidBuildService), while the rest is just "allowed". So yes, presence of "user_defined_values" is understood, and it's not that easy to map legacy build into new structured build (for that, you should know all strictly defined fields, and parse them out).
