By default, .mmp files that include FEATUREVARIANT will generate binaries for

both "normal", non-binary variant, build configurations and binary variant

build configurations.

In order to ensure that only invariant binaries are created for invariant

build configurations, and variant binaries for variant build configurations,

the optional setting FEATUREVARIANTSAFE can be used. FEATUREVARIANTSAFE can be

set via an os_properties.xml file and, when set, variant binaries will no

longer be created for invariant build configurations.
