`make menuconfig` fails when the parent directory contains spaces.

[Hoshmand M. Qadir]

if the parent directory contains spaces, make menuconfig fails

$ make menuconfig
No change to configuration in '/media/test/Creality Ender 3 Pro/klipper/.config'
Loaded configuration '/media/test/Creality Ender 3 Pro/klipper/.config'
---snip----

when replacing spaces with underscores or replacing them with nothing it works fine.

 $ make menuconfig
