Requested .sh

For fun, I installed OpenBSD 7.0 (current newest) on an old PowerMac G5 sitting
in a room collecting dust.  It comes with:

OpenBSD clang version 11.1.0
Target: powerpc-unknown-openbsd7.0
Thread model: posix
InstalledDir: /usr/bin

I tried to build CMake from its git master, and got:

```
