Add OBJECT_FILE_DIR rule placeholder for compilation lines

Some compilers do not offer an option to specify the path to the object
file, but rather only to the directory in which to place the object
file.  See issue 14876 for some examples.  Add a new OBJECT_FILE_DIR
placeholder to specify the directory containing the object file for the
current compilation.  This may differ from the main target OBJECT_DIR
when the object corresponds to a source in a subdirectory.

Xcode: Fix single-configuration generation for version 1.5

In commit 84fdc992 (stringapi: Pass configuration names as strings,
2014-02-09) a few code paths for the Xcode 1.5 single-configuration
generator were not updated to use an empty configuration name instead of
a NULL pointer when no configuration is specified in CMAKE_BUILD_TYPE.
Fix them now.
