If I understand you correctly, I think you can use Python to=C2=A0
do it (if your GDB has Python support).

Something like putting following your .gdbinit (or to system-wide
init script):

---8<----
python
import os

path_from_env =3D os.environ.get('GDB_DEBUG_FILE_PATH')
if path_from_env is not None:
    old =3D gdb.parameter('debug-file-directory')
    new =3D old + ":" + path_from_env
    gdb.set_parameter('debug-file-directory', new)

end
---8<----
