Fourth incremental variable. Adds the getauxval_fix.c shim from the legacy wzp-android crate (which has been shipping with it for months without issue) to our cc::Build on Android. The file defines a single getauxval() function that delegates to bionic's real runtime implementation via dlsym — this is needed because rustc links compiler-rt's broken static getauxval stub that SIGSEGVs in .so libraries loaded via dlopen (reads __libc_auxv which is NULL). Not imported from Rust. Goal: verify that adding a second C static archive (and especially one that overrides a libc-ish symbol) doesn't regress the working build.
