    automation: special configure flags for musl-based systems
    
    QEMU upstream builds with warnings when libc is musl:
    
      #warning redirecting incorrect #include <sys/signal.h> to <signal.h>
    
    Disable -Werror by passing --disable-werror to the QEMUU config script
    if libc is musl.
    
    hvmloader doesn't build on musl systems today. Disable any guest
    firmware build.
