Start with compiler-rt/cmake/Modules/AddCompilerRT.cmake at the reported add_library call and compiler-rt/lib/profile/CMakeLists.txt around line 283. Reproduce the runtimes CMake configuration for powerpc64 from the Debian build log, then verify that the RTInterception.powerpc reference resolves and clang_rt.profile_rocm-powerpc configures without the missing-target or no-sources errors.
