Please use a Linux system to build the Linux kernel on for your first
attempt.  Trying to get it to build on a non-Linux system is not always
a trivial exercise as you are finding out.

And again, the problem is in your filesystem type you are building on,
it is case-insensitive.  Fixing that is the problem here, it is not a
Linux kernel specific thing.

good luck!
