    d: give dependency files better filenames [PR118477]
    
    Currently, the dependency files for root-file.o and common-file.o were
    both d/.deps/file.Po, which would cause parallel builds to fail
    sometimes with:
    
      make[3]: Leaving directory 
'/var/tmp/portage/sys-devel/gcc-14.1.1_p20240511/work/build/gcc'
      make[3]: Entering directory 
'/var/tmp/portage/sys-devel/gcc-14.1.1_p20240511/work/build/gcc'
      mv: cannot stat 'd/.deps/file.TPo': No such file or directory
      make[3]: *** 
[/var/tmp/portage/sys-devel/gcc-14.1.1_p20240511/work/gcc-14-20240511/gcc/d/Make-lang.in:421:
 d/root-file.o] Error 1 shuffle=131581365
    
    Also, this means that dependencies of one of root-file or common-file
    are missing when developing.  After this patch, those two files get
    assigned dependency files d/.deps/root-file.Po and
    d/.deps/common-file.Po respectively, so match the actual object
    files in the d/ subdirectory.
    
    There are other files with similar conflicts (mangle-package.o,
    visitor-package.o for instance).

            * Make-lang.in (DCOMPILE, DPOSTCOMPILE): Use $(basename $(@F))
            instead of $(*F).
