Disable documentation if utilities are missing
* macros/mm-doc.m4 (_MM_ARG_ENABLE_DOCUMENTATION): If one of the
required utilities for the documentation build is missing, display
a warning message and disable the documentation build, but otherwise
continue execution. However, do abort with an error if the configure
option --enable-documentation was used explicitly.
