If roms/seabios/Makefile is not present, the configure script
is not creating the roms/seabios directory anymore (commit
5dce7b8d8c, "configure: remove DIRS", 2021-12-18); thus, creating
roms/seabios/config.mak fails.

The easiest thing to do is to not create the file, since it will not
be used.

I think you can now simply remove the "for" loop line by setting 
config_mak=roms/seabios/config.mak here.
