It is OK for older binutils to ignore these new types.  You just don't
get new features
with older binutils.

I will add them to master branch.  And there may be new property types after
binutils 2.32 is released.  "make check" will fail on binutils 2.32
branch.  In fact,
"make check" fails on binutils 2.31 branch.
