Subject: [PATCH] minimal-bootstrap: drop patchelf compiler reference

Static patchelf does not need build-compiler paths in debug or source metadata. Add deterministic compiler flags and disallow references to the bootstrap compiler.

Size impact against upstream/staging:

- patchelf-static closure: 167.634 MiB -> 1.237 MiB (-166.397 MiB)

Assisted-by: codex with gpt-5.5-high
