Since the defconfig file name is configurable (by means of
BR2_DEFCONFIG), I don't think we should do anything special with it. So
I don't think it should be in .gitignore and I don't think we should
remove it upon "make distclean".

If we were do "rm -f $(BR2_DEFCONFIG)" to always remove the user
configured defconfig, then it would remove configs/<foo>_defconfig if
you started from that defconfig and do a "make distclean". Not good.
And we can't have user-configurable file names in .gitignore I believe.

So I'm personally in favor of keeping things as they are today, and
therefore reject the patch proposed by Károly.

Best regards,

Thomas
