Question about multi-versioning. Say I want to 1. build flang, 2. build flang_rt with -O0 -g out of tree, 3. build flang_rt with -O3 out of tree.

When I am trying that with the patch, step 3. build and install libflang_rt.a override the ones from setp 2. Is there a way/option to use the out-of-tree build directory as the output directory for the build libflang_rt.a to build different versions instead of the llvm/clang build directory?

Note: I know it is currently not possible to do that, and I am asking because your patch is a step towards that, which is great!
