Woohoo... Stop!
We're speaking of building the toolchain components statically!
That is: gcc and binutils, period. (yes, and gdb if you want).

The glibc that is built with the toolchain is not what we are speaking
about! And this is this glibc that has a 'minimum supported kernel
version'.

But I have to agree that it gets messy to speak about this stuff! ;-)

See above, irrelevant, we're speaking a bout the *host* C library, not
the target's C library.

Hope this makes it clear. :-) (BTW, I just saw Khem answered the same).
