[Buildroot] [git commit] tpm2-tools: allow building without stack smashing protection (SSP)

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=428dfe71f337a5de4540d57a244442d64b2d8e75
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Disable SSP if the toolchain does not support it. This must be done
explicitly because configure enables hardening by default but doesn't
contain a link test, so it doesn't detect when libssp is missing.
