* [Bug preprocessor/15462] New: -M writes the filename without full path

I have several subdirectories in my project and build files for it using the
full path name. The makefile generates automatic dependencies using -M thus:
> c++ -I ~/include -M core/address.cc
address.o: core/address.cc core/address.h
/home/msharov/include/ustl.h \
/home/msharov/include/ustl/uspecial.h \
/home/msharov/include/ustl/memblock.h \
/home/msharov/include/ustl/memlink.h \
/home/msharov/include/ustl/cmemlink.h
and so forth. The problem is that the target name - address.o - is written
without the path, so the dependencies end up being for ./address.o rather than
core/address.o, which means that make never rebuilds the files in the
subdirectories. While I suppose it is possible to have the subdirectories as
subprojects generating .a packages which are then linked together as a
workaround, -M really should include the full path name for the target.

Invalid as if you compiled with -c it would output address.o and not core/address.o, you have to supply
-MQ core/address.o to get the right path.
