Debian's build hardening toolchain options produce binary artifacts
that are more resistant to compromise. The most visible change for
notmuch today is likely to be the addition of the "bindnow" linker
flag, which contributes to making the "Global Offset Table" fully
read-only.
See https://wiki.debian.org/Hardening for more details.
