**Use case**

**Describe the solution you'd like**

There are multiple ways to prevent LD_PRELOAD:

- link statically with musl to prevent any chance for LD_PRELOAD working;
- add some flag to the binary like capabilities or setuid to also prevent LD_PRELOAD working;
- don't allow it with some env variable;
- implement our own dynamic loader.

Also possible workaround:

- check if LD_PRELOAD is set very early at program startup. If it is, reset it and exec ourself with the same argc, argv.
