When installing runtimes with install-runtimes-stripped, we don't want to just strip them, we also want to preserve the debugging information for potential debugging. To make it possible to later find the stripped debugging information, we want to use the .build-id layout: https://fedoraproject.org/wiki/RolandMcGrath/BuildID#Find_files_by_build_ID That is, for libfoo.so with build ID abcdef1234, the debugging information will be installed into lib/debug/.build-id/ab/cdef1234. llvm-objcopy already has support for stripping files and linking the debugging stripped output into the right location. However, CMake doesn't support customizing strip invocation for the *-stripped targets. So instead, we replace CMAKE_STRIP with a custom script that invokes llvm-objcopy with the right command line flags.
