Trying to get LLVM compiling as a static build
The configure command I am using is
```bash
cmake -S . -B build -G Ninja \
-DLLVM_BUILD_STATIC=ON \
-DLLVM_LINK_LLVM_DYLIB=OFF \
-DCMAKE_BUILD_TYPE=Release
```
Configure fails to find a bunch of required `unistd.h` symbols, as well as other header functions also.
Here is the configure output
```bash

CMake Error at cmake/modules/CheckAtomic.cmake:59 (message):
Host compiler appears to require libatomic, but cannot find it.
Call Stack (most recent call first):
cmake/config-ix.cmake:487 (include)
CMakeLists.txt:1041 (include)
-- Configuring incomplete, errors occurred!
```
When configuring as a shared library, configure completes successfully (and does find all required functions, such as `getpagesize`):
```bash
cmake -G Ninja -B build \
-DCMAKE_INSTALL_PREFIX=llvm-macos-arm64 \
-DCMAKE_BUILD_TYPE=Release \
-DLLVM_BUILD_LLVM_DYLIB=ON \
-DLLVM_BUILD_STATIC=OFF
```
Something is definitely broken with the static configure.
If I configure both shared and static, the configure also fails with the same output.
