Subject: [PATCH] [CMake] Fix building on Haiku and Solaris after
 c0d5d36dda04cdd409aabc015da0beb810842fcd (#78084)

Haiku and Solaris need some additional libraries after the commit
c0d5d36dda04cdd409aabc015da0beb810842fcd

Otherwise fails to link a whole bunch of the tools and other binaries
with undefined symbols with accept() and connect().

I did a static and dynamic build on illumos and a dynamic build on
Haiku.

```
-DLLVM_ENABLE_PROJECTS='clang;clang-tools-extra;lld;mlir'
```
and on illumos
```
-DLLVM_ENABLE_RUNTIMES='openmp'
```
