    automake: display whether sleep supports fractional seconds as yes/no.
    
    https://lists.gnu.org/archive/html/automake/2024-07/msg00003.html
    
    * m4/sanity.m4 (_AM_SLEEP_FRACTIONAL_SECONDS): Set
    am_cv_sleep_fractional_seconds to yes/no, not true/false,
    for consistency with other results.
    Also "quote" this and other $am_cv values.
    (_AM_FILESYSTEM_TIMESTAMP_RESOLUTION): Test for yes/no.
    * t/ax/test-defs.in: Set am_cv_sleep_fractional_seconds to 'no',
    not 'false'.
