I have simplified the [BuildOptions] section. Since the first use for these
uses a '==', all flags inherited from tools_def.txt or the DSC file are
thrown out. This is required to build this submodule that does not like
the EDK II default Base.h definitions. The only use case today for this
component is in host-based unit testing to support gmock. It may be
possible to extend the support of the lib to target based environments
for IA32/X64, but would require more work on getting the build to be
compatible. For now, I have changed the MODULE_TYPE to HOST_APPLICATION
as that is the only env supported now.
