For libseccomp, it looks like it doesn't need a rebuild; it appears to
only reference the symbol in its header (which is what causes this
problem for other packages that pull in that header); in its code, the
only reference is where its syscall number is defined is inside its
ppc64_syscall_table (and ppc_syscall_table), where it is defined
correctly.

I still don't understand why libseccomp ever decided to define
__NR_pkey_mprotect to a negative number (if the kernel header doesn't define
it) in its public header file. IMHO that should be done in its code, or at
least in a private header file.
