To test the generated headers, you'll need to full build mode.  You can use the following cmake command from our build bots:
```
$ cmake ../llvm -GNinja -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++ -DCMAKE_BUILD_TYPE=Release "-DLLVM_ENABLE_PROJECTS=llvm;libc;clang;compiler-rt" -DLLVM_LIBC_INCLUDE_SCUDO=ON -DLLVM_LIBC_FULL_BUILD=ON
$ ninja libc && ninja check-libc
```
