v1->v2:
 - add patches for 2.23/2.25, requested by Arnout

In the past I remember some discussions about removing version
selection for all C libraries. Any idea why we still have more than
one glibc version?

[Buildroot] [PATCH v2] glibc: fix sh4 compile issue

[Thomas Petazzoni]

Hello,

I've applied, but there were several issues:

 - First, you still don't use Git to format patches. Please use Git to
   format patches.

 - If you had done that, then the patches would have automatically had
   the original description, which we want to have in Buildroot.

 - Finally, for the 2.23, there was already a 0001-<something> patch,
   so the numbering was wrong.

I've fixed up those issues, see
https://git.buildroot.org/buildroot/commit/?id=5f2cff973a8a64411d85ccb9d5c9a40962d67552.

Historical reason I'd say.

Thanks!
