From: "mark.yang" <[email protected]> When using Clang toolchain with LTO enabled, static libraries (.a) contain LLVM bitcode objects instead of ELF objects. dwarfsrcfiles cannot process these files and fails with "not a valid ELF file" error.
Rather than catching the error message, guard the dwarfsrcfiles call by checking for the specific conditions: static library (using is_static_lib() magic check) + clang toolchain + lto in DISTRO_FEATURES. When all conditions are met, skip the call silently.
