Unable to build instances for 4 Noto fonts (related to include path handling fix)

Since handling of includes was changed in fontmake (or one of the libraries it uses) I'm unable to build instances for the following fonts:

- NotoSansHanifiRohingya
- NotoSansMedefaidrin
- NotoSerifNyiakengPuachueHmong
- NotoSerifYezidi

All the sources I use for this build are in https://github.com/googlefonts/noto-source/tree/main/src

The symptoms of the failure (for example for _fontmake -m src/NotoSerifYezidi/*.designspace -i -o otf ttf_ ):

I need help fixing the sources or fixing something in the fontmake (or libraries).

Note that I can build the variable fonts but I'm not certain anymore that it properly deals with the external feature file.

I believe that the issue is that "fontmake et al" creates build instance_ufos in a separate build directory. However, the features.fea in each UFO includes file that is in the .. directory in the sources which is not copied to the build UFO structure.

PS. For NotoSerifNyiakengPuachueHmong the file path is somewhat different but the failure is the same

PS2. I believe I can copy the common feature file into each instance UFO and this would fix the issue but the designer of the font established a common feature file for all instances and copying this file into each instance would fore us to maintain multiple copies of the same info
