The problem is that only 2 of 3 Architecture lines contain the list of
supported architectures, there is still an arch-any line.
The nicer fix would be to make libnuma provide stubs when the respective
syscalls are not there.
BTW, on arm the culprit is:
http://git.kernel.org/linus/d80ade7b323152672bf66e74ec11c324332f6d1e
So something like:
diff --git a/syscall.c b/syscall.c
index 4589b8547697..2d3a468f1ac1 100644
--- a/syscall.c
+++ b/syscall.c

long WEAK move_pages(int pid, unsigned long count,
should fix the build failure.
I guess upstream doesn't care about non-linux architectures. To support
them probably the easiest would be to make syscall a stub setting errno
to ENOSYS and returning -1.
