[Buildroot] Where is mtd/mtd-user.h supposed to come from?

Rather belatedly I realise that I am seeing the same problem. When the 
kernel headers are installed I get mtd-user.h in 
toolchain/linux/include. Also when I build mtd-utils the header is in 
build/mtd_orig/include. However it does not get copied in 
staging/usr/include so any apps I write that use the header fail to compile.

I have previously fixed this my adding a rule that copies the headers 
from build/mtd_orig/include when the mtd package is built.

Is this a good way to do this? Why aren't all the kernel headers made 
available in staging/usr/include? How would anyone else fix this?

Thanks
