Looks like you're building a separate kernel module for Android.

Kernel modules are required to be built without position-independent code generation(PIC). If you're using an Android toolchain, the kernel's Makefile should have KBUILD_CFLAGS += -fno-pic. Or, a better solution would be using a toolchain that doesn't target Android(hence not using PIC by default).

As a temporary solution, please try adding ccflags-y := -fno-pic under exfat-objs on Makefile.

Closing as this isn't an issue directed from this project.
