    build: guess availability of monotonic clock for cross compilation · c601c8fa
    Helmut Grohne authored
    When cross compiling, the value of MONOTONIC_CLOCK would be "cross
    compiling", because AC_RUN_IFELSE doesn't work. However when enabling
    wayland, a monotonic clock is required and configure aborts.
    
    We change detection of CLOCK_MONOTONIC to degrade it gracefully from a
    run check to a declaration check in case of cross compilation based on
    the assumption that most systems will have a monotonic clock and those
    that don't won't be able to run Xwayland anyway. The trade-off
    essentially is either "always fail cross compilation" or "produce an
    unusable Xwayland for unusual platform" and this commit switches to the
    latter.
