Indeed, I just spotted that there is nothing in the v7 patch that looks like
this:

    d_target_objs="rs6000-d.o"

If I recall right, that's because the powerpc configure path adds rs6000-d.o
using this assignment:

    d_target_objs="${d_target_objs} ${cpu_type}-d.o"

Which is too absent from the v7 patches.  So ig you look at that particular
hunk, what you are searching for in the config.gcc file is the following line:

    cxx_target_objs="${cxx_target_objs} ${cpu_type}-c.o"

You want to add the d_target_objs assignment *after* that.

The untested patch series just adds architectures not covered by CI, there's
nothing powerpc related there.  We already have powerpc64le builds tested, so I
know that everything more or less is fine on master.  The problem is that that
specific the change did not make it to other branches it seems.
