Subject: [PATCH] stdenv: linux: inherit nukeReferences through
 xgcc/stage2/stage3
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

nukeReferences was rebuilt at every stage where it appeared (xgcc, stage2,
stage3 — 3 redundant builds beyond stage1's initial build). It is used only
at build time (to scrub references from libidn2/libunistring at stage2),
never appears in the final stdenv's runtime closure, and its outputs are
not propagated into other final-closure derivations.

Adding it to the inherit list at xgcc, stage2, and stage3 collapses the
chain to a single stage1 build. Stage4 still produces its own nukeReferences
through the regular package set; that one is unused by the final stdenv.

Build-only dependency, so this is safe with respect to the
`disallowedRequisites` check on the final stdenv-linux.
