Why do you think you really need glibc? Given how old dce legacy
codebases are you just need a basic libc with your threading model. You
could for example take uclibc as a library that is simple and supports
threading and hack draft 4 posix threads into them. no one forces you
to use glibc for your oddish broken legacy garbage.
