Merge #17686: build: add -bind_at_load to macOS hardened LDFLAGS
c78b123982d59fe2d633659f23d6893de627f3f6 build: add -bind_at_load to hardened LDFLAGS (fanquake)
Pull request description:
This performs the same function as `-Wl,-z,now`, except for ld on macOS.
You can check the binaries using `otool -l`, and looking for the `LC_DYLD_INFO_ONLY` section; `lazy_bind_off` and `lazy_bind_size` should both be 0.
This seems to be the case with our current release binaries. However we can make the check, and applying the flag explicit in configure.
man ld:
```bash
-bind_at_load
Sets a bit in the mach header of the resulting binary which tells dyld
to bind all symbols when the binary is loaded, rather than lazily.
```
TODO:
- [ ] Follow up with `MH_BINDATLOAD` flag.
