When building ct-ng with (e)glibc >= 2.11 and building either a
statically linked toolchain or the normal dynamically linked
toolchain, I still notice that the elf OSABI is "(GNU/Linux) - 3" and
not "(SYSV) - 0"

grep '(GNU/Linux)'

I have tried adding binutils-2.20.51 (snapshot) to my local version of
ct-ng, but this produced the same results.

Does anyone have suggestions on how to (e)glibc to build as "(SYSV)"
and not "(GNU/Linux)"?
