[ELDK] glibc change for eldk 3.1.1

So?  What did you prove that it works with NPTL + 2.6.

Exactly.

But this is only _half_ the difference.  Do you expect that the other
difference vanishes into thin air?

Also changing glibc means you have to recompile _all packages inside
ELDK_ against the new toolchain, effectively building your own private
version of the ELDK.

I'm really not sure how you come to feel that changing glibc is "less
risky".  Do you have any experience with such an operation, i.e. did you
_actually_ do such a switch before in a different project?

You keep saying this, but let me tell you that if you have a working 2.4
and 2.6 kernel, then this switch is not so problematic as it seems _for
userspace_.  

Of course if you have an out-of-tree 2.4 kernel and need to forward port
all those changes, it will have a lot of impact.

Cheers
