We need a way to pass flags to rombuilds in Raptor via extension flm interfaces, so that the CPP pass of the rom input files can be informed what toolchain we are building with and conditionally include or exclude files depending on whether the toolchain could build them.

// Description:
// e32test\earlyextension\earlyextension.cpp
// This is to test the registration of early extension and will do the following
// - Constructing the static data in VariantInit0 (the main extension object)
// - In Init3 entrypoint allocating space in Kernel Heap to store the time stamp obtained
// calling Kern::SystemTime().
// - Supplying one exported function to allow reading the time stamp.
// 
//
