    tools/libtool: 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.
    
    Override an automake variable "am__CONFIG_DISTCLEAN_FILES"
    and related variables for their dependencies
    in order to prevent removing config.status and other configure files
    so that configure stage does not need to be ran twice.
    
    Automake with modified rules must be ran
    in order to generate a Makefile that does not delete itself.
