Steps to reproduce the problem:
We obtain our toolchain from here:

https://pantheon.corp.google.com/storage/browser/chromiumos-sdk/2017/08/

Snapshot: 163007.

And our sysroot from:

https://pantheon.corp.google.com/storage/browser/chromeos-prebuilt/host/amd64/amd64-host/chroot-2017.08.01.163007/packages/cross-armv7a-cros-linux-gnueabi/

We notice that these libs don't have a stack canary:

Full RELRO No canary found NX enabled libcrypt-2.23.so
Full RELRO No canary found NX enabled libdl-2.23.so
Full RELRO No canary found NX enabled libm-2.23.so
Full RELRO No canary found NX enabled libnsl-2.23.so
Full RELRO No canary found NX enabled libnss_compat-
2.23.so
Full RELRO No canary found NX enabled libnss_dns-
2.23.so
Full RELRO No canary found NX enabled libnss_files-
2.23.so
Full RELRO No canary found NX enabled libpthread-
2.23.so
Full RELRO No canary found NX enabled librt-2.23.so
Full RELRO No canary found NX enabled libutil-2.23.so

What is the expected behavior?
