[flang-commits] [flang] [flang] Fix distribution build of Fortran builtin/intrinsic modules. (PR #184204)

[Daniel Chen via flang-commits]

https://github.com/DanielCChen created https://github.com/llvm/llvm-project/pull/184204

Currently, `-DLLVM_DISTRIBUTION_COMPONENTS="flang-module-interfaces"` doesn't work. It failed to build the Fortran builtin/intrinsic modules as distribution build, `install-distribution`.
This PR is to fix that.
