Subject: [PATCH] minimal-bootstrap: trim binutils-static output

Drop unused installed libraries and headers, avoid building unused gprof/libctf components, and replace duplicate target-prefixed tools with symlinks while keeping the conventional paths available.

Size impact against upstream/staging:

- binutils-static closure: 42.482 MiB -> 21.093 MiB (-21.389 MiB)

Assisted-by: codex with gpt-5.5-high
