    Hi everyone,

I am testing compiler-rt in LLVM_ENABLE_RUNTIMES along with libcxx and libcxxabi. I am coming across certain problems regarding install step of compiler-rt builtins.

Previously with compiler-rt in LLVM_ENABLE_PROJECTS we used to get the libclang_rt.builtins-x86_64.a in the folder **clang/16.0.0/lib/linux**. We get both the libclang_rt.builtins.a and libclang_rt.builtins-x86_64.a in the same folder clang/16.0.0/lib/linux.

Now when I am trying to use compiler-rt in LLVM_ENABLE_RUNTIMES along with libcxx & libcxxabi the install step actually installs only the libclang_rt.builtins.a in folder **clang/16.0.0/lib/x86_64-unkown-linux-gnu**  but not libclang_rt.builtins-x86_64.a in the same folder. I am assuming that libclang_rt.builtins-x86_64.a will architecturally be the same as libclang_rt.builtins.a and so libraries should adapt to link to this rather than libclang_rt.builtins-x86_64.a.

Since we had shipped the library which links with the libclang_rt.builtins-x86_64.a, I would like to have this library always installed in the installed path of clang/16.0.0/lib/x86_64-unknown-linux-gnu folder but the problem is using compiler-rt in LLVM_ENABLE_RUNTIMES seldom installs the libclang_rt.builtins-x86_64.a and some other -x86_64.a builtins also.

Any information or help regarding how to resolve this thing?
