Subject: [PATCH] chrony: fix build failure for arma9

    Eliminate references to syscalls not available
    for ARM_EABI.  Also add a dependency on libseccomp
    which is needed for scfilter to work.

    Set PACKAGECONFIG to not enable scfilter, since
    kernel CONFIG_SECCOMP is unlikely to be set.  This
    aligns the usage of libseccomp with that of other packages.

    Upstream-Status: Pending

    Refresh patch for new upstream version.
