.gitignore does not ignore Makefile

I have the following .gitignore file in patch arm/arm64/boot/dts:

*.dtb qcom qcom.orig

When I do a git status, I see this:

    modified:   .gitignore
    modified:   qcom/Makefile

All of the other files in arm/arm64/boot/dts/qcom are being ignored, as request. However, the file "Makefile" is not being ignored. Why? What's so special about "Makefile" that git refuses to ignore it?
