This reverts commit42eb7db188. This reland3fbb037d03(#209922). Under CMake 4+, calling add_library(... SHARED IMPORTED) on a target platform that lacks dynamic linking support triggers a fatal error. This becomes an issue when building LLVM and runtimes for baremetal targets like armv6m-none-eabi. This patch adds the option "LLVM_OMIT_EXPORTS_FROM_CONFIG" in LLVM. When used in sub builds like LLVM runtimes, it makes CMake to skip including the LLVM and Clang exports. This mitigates the CMake 4 errors on baremetal runtimes.42eb7db188originally apply this flag on all runtimes build and causing issues on runtimes like intel-sycl-gpu, amdgpu-offload-ubuntu-22-cmake-build-only. This PR only set this flag when the target platform lacks shared library support.
