    tools/coreutils: add maintainer-clean to clean target
    
    Use the clean recipe during build, so that files already
    generated by the bootstrapping within the release are removed
    before the bootstrap script is run again.
    
    Automake with modified rules must be ran
    in order to generate a Makefile that does not delete itself.
    
    Override an automake variable "am__CONFIG_DISTCLEAN_FILES"
    in order to prevent removing config.status and other configure files
    so that configure stage does not need to be ran twice.
    
    Redefine MAINTAINERCLEANFILES with Make functions
    to avoid deleting the targets of gettext and gperf rules.
    
    In order to prevent an inconsistent state of `install`
    since this utility must always be available as a prerequisite,
    do not allow it to be removed.
    
    Instead of preventing the removal of the config.h header,
    the Makefile supports regenerating it quickly.
