I'm trying to do a release build with flang on the GitHub Action MacOS X86_64 runners and it is failing with this error:
```
[338/2224] Generating ../../../../include/flang/__fortran_builtins.mod
FAILED: include/flang/__fortran_builtins.mod /Users/runner/work/llvm-project/llvm-project/build/tools/clang/stage2-bins/include/flang/__fortran_builtins.mod

dyld[6699]: unknown imports format

```
I think it may be possible that this error is a symptom of running out of memory. Does this command use a lot of memory?
### How To Reproduce
```
cmake -G Ninja -S llvm -B build \
-DLLVM_RELEASE_ENABLE_PGO=OFF -DBOOTSTRAP_COMPILER_RT_ENABLE_IOS=OFF -DBOOTSTRAP_DARWIN_osx_ARCHS=x86_64 -DBOOTSTRAP_DARWIN_osx_BUILTIN_ARCHS=x86_64 \
-C clang/cmake/caches/Release.cmake \
-DBOOTSTRAP_LLVM_PARALLEL_LINK_JOBS=1 \
-DBOOTSTRAP_CPACK_PACKAGE_FILE_NAME="LLVM-19.1.0-rc1-macOS-X64"
ninja -C build stage2-package
```
