>From stdenv/generic/setup.sh:

patchELF() {
    # Patch all ELF executables and shared libraries.
    header "patching ELF executables and libraries"
    find "$prefix" \( -name "*.so*" -o \
        \( -type f -a -perm +0100 \) \
        \) -exec patchelf --shrink-rpath {} \;
    stopNest
}

Note that patchelf skips things that aren't ELF images.
