Apparently a zero byte file size leads to "could not open" warnings.
Adding a single comment to the file removes the warnings displayed
after compilation.
To prevent overwriting a user supplied config-mycompat.h the file
is only created if it does not already exist.
Also fix for possible spaces in the path.
Works without warning when using both the do-it-all build script
as well as manual operation via make targets.
