Why? Because it will feel so good when you stop trying it?
- Removing comp*.tgz from an OpenBSD platform will not improve security. Anyone who can gain shell and network access can bring a compiler or any other needed tool with them.
- The build environment is unique. The built-in gcc tool chain is customized to include OpenBSD-specific features, such as ProPolice.
- Cross compilation of any kind -- even OpenBSD to OpenBSD across architectures, is unsupported. The cross compilation tools used by developers are only used when migrating to new archs, and are neither kept up to date nor documented, specifically to prevent users from attempting to use them.
