Always show "Set Current Build Configuration" in pallete

When building out of tree, whether the extension is in fullFeatureSet or
not depends on which build configuration is chosen.

The workspace does not have a Makefile, but one of the builddirs in a
configuration does. Allow that configuration to be selected,
unconditionally on the currently selected configuration.
