[ELDK] glibc change for eldk 3.1.1

[Levend Sayar]

Hi, Detlev,

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

Yes it works on NPTL + 2.6. Also it works on RedHat 9.0 which is based on 2.4.20 kernel + 2.3.2
 glibc + 0.29 NPTL. Buy you said this is backport. OK.

You are right.

I did not notice this. If this is case, be sure I will not do this.
I though 2.3.1 -> 2.3.3 change will not change too much.

No I did not try this before.

I changed kernel a little bit for CompactFlash, fpga, spi rtc support.
I did not use ELDK 4.2. Just downloaded. I want to try it later. Kernel change
is not problematic for userspace of course. But we have many drivers. We have to recompile them.
And I did not write all the drivers. So I did not want to bother other developers in my team for this extra work.
