--- Comment #1 from Tom de Vries <vries at gcc dot gnu.org> ---
-Wl,-ctf-variables improves things for me:
...
$ objdump --ctf outputs/gdb.base/ctf-constvars/ctf-constvars | grep vox
    vox -> 0x3: (kind 11) volatile char (size 0x1) (aligned at 0x1) -> 0x1:
(kind 1) char (format 0x3) (size 0x1) (aligned at 0x1)
    0x21d: vox
...

That still doesn't fix things:
...
$ gdb -q -batch outputs/gdb.base/ctf-constvars/ctf-constvars -ex "print vox"
'vox' has unknown type; cast it to its declared type
...
because the dwarf info is in the way.

After stripping the dwarf info:
...
$ strip --strip-debug outputs/gdb.base/ctf-constvars/ctf-constvars
...
we have:
...
$ gdb -q -batch outputs/gdb.base/ctf-constvars/ctf-constvars -ex "print vox"

$1 =3D 66 'B'
...
