The presense of PdbPointer (PDB file name) is not an error. Hence, the
debug message should be categorized as VERBOSE or INFO. However, the
DEBUG_VERBOSE is more appropriate since the PDB file name is already
output by the PeCoffLoaderRelocateImageExtraAction() function with the
inline "add-symbol-file" when a platform uses the library instance
DebugPeCoffExtraActionLib.
