and I should add this sanity check:

--8<---------------cut here---------------start------------->8---
address@hidden:/tmp/nix-build-glibc-2.21.drv-0/build/elf$ readelf -a ld.so.new 
| grep RUNPATH
 0x0000001d (RUNPATH)                    Library runpath: 
[/gnu/store/fbdjazgwy3zyx8qc5z4ag0j78k2d7raw-glibc-2.21/lib]
--8<---------------cut here---------------end--------------->8---
