That's because of a (old) limitation of the kconfig language: you can't have
a choice entry be present in two different choices. Well, that's not longer
true. If the choice has a name, then you can duplicate it, with the exact
same entries in it. But we do not do that in crosstool-NG.

So this means we can not have LIBC_V_2_10 present both in the glibc version
choice, and in the eglibc version choice.

It should not happen when using scripts/addToolVersion.sh to add new versions.
I did not think not renaming the existing entries would be an issue, though.

I can understand. I will review Bryan's patchset right now...

Thank you for spotting the issue.
