So drop this part of the documentation. cris is broken - I will send a patch to fix this. In reality um does not support exporting headers - but it makes no sense either. We do not want to do anything special just to mention that um is not included. > The command "make headers_install_all" exports headers for all architectures > simultaneously.

I have seriously considered dropping the "headers_install_all" target. It does not make any sense as some files are optional for the individual archs and only pure luck will define if the relevant fiels are included or not. We would still like the "headers_check_all" feature but this is better done in a small shell script than as it is today where we need special handling to support it in Makefile.headersinst - and it adds complexity to the top-level Makefile which we shall avoid. But this is unrelated to your documentation clean-up.
