    libsanitizer: Remove cyclades from libsanitizer

    The Linux kernel has removed the interface to cyclades from
    the latest kernel headers[1] due to them being orphaned for the
    past 13 years.

    libsanitizer uses this header when compiling against glibc, but
    glibcs itself doesn't seem to have any references to cyclades.

    Further more it seems that the driver is broken in the kernel and
    the firmware doesn't seem to be available anymore.

    As such since this is breaking the build of libsanitizer (and so the
    GCC bootstrap[2]) I propose to remove this.
