Add an option that when passed, will disable hardening options, and
pass `--disable-hardening` through to configure. Due to the way
we link libssp for Windows builds, they now fail (after #27118),
if building with depends, and configuring with --disable-hardening.
See:
https://github.com/bitcoin/bitcoin/pull/27118#issuecomment-1492606272.
This change would add a depends opiton such that, if someone wants to
build with, for windows, without hardening, they can do so. This may
also be useful when building for debugging.
We now use a script named gen_id to generate the base build_id/host_id.
This solves 2 problems:
1. GNU Make special-casing exit code 127 (command not found) meant that
warnings about missing tools would propagate to the user's terminal
and broke our opportunistic build_id construction.
2. This change ensures that we don't have arbitrary characters in our
make variables that would be misinterpreted by Make.
See comments in depends/Makefile and depends/gen_id for more
information.
