1. do another backup
2. take your last good binary package and unpack it in the root
directory - it is an "image" of that package as it sits in the file system.
3. rebuild that version of glibc by overiding emerge - comment out "die
"aborting to save your system" in /usr/portage/eclass/toolchain-glibc.eclass

I have done this a couple of times with gcc (when manual deletes have
gone rogue) but it should work with glibc as you have not recompiled any
new packages.
