-Subject: [PATCH] Fix profiler_builtins build script to handle full path to
- profiler lib
-
-LLVM_PROFILER_RT_LIB may be set to an absolute path (e.g., in Fedora builds),
-but `-l` expects a library name, not a path. After #138273, this caused builds
-to fail with a "could not find native static library" error.
-
-This patch updates the build script to split the path into directory and
-filename, using `cargo::rustc-link-search` for the directory and
-`cargo::rustc-link-lib=+verbatim` for the file. This allows profiler_builtins to
-correctly link the static library even when an absolute path is provided.
