BLE-Cordio-Stack: Unable to disable ble features

[DBS06]

Description of defect

I tried to disable a couple of ble-features to reduce the code size. I set the following in the mbed_app.json:

            "ble.ble-feature-extended-advertising": false,
            "ble.ble-feature-gatt-client": false,
            "ble.ble-feature-gatt-server": true,
            "ble.ble-feature-periodic-advertising": false,
            "ble.ble-feature-phy-management": false,
            "ble.ble-feature-privacy": false,
            "ble.ble-feature-secure-connections": false,
            "ble.ble-feature-security": true,
            "ble.ble-security-database-filesystem": false,
            "ble.ble-security-database-kvstore": false,
            "ble.ble-feature-signing": false,
            "ble.ble-feature-whitelist": false,
            "ble.ble-role-central": false,
            "ble.ble-role-observer": false,
            "ble.ble-role-broadcaster": true,
            "ble.ble-role-peripheral": true,

But if I do this I get the following compile-error:

/xxx/mbed-os/connectivity/FEATURE_BLE/libraries/ble-api-implementation/source/SecurityManagerImpl.cpp: At global scope:
