check-abi failure with sys_errlist

[Andreas Jaeger]

Running check-abi on Linux/x86-64 I get a failure now:

Andreas, might this be related to your change:
2012-02-19  Andreas Schwab  <schwab@linux-m68k.org>

	* manual/errno.texi (Error Codes): Add EHWPOISON entry.
	* sysdeps/unix/sysv/linux/bits/errno.h (EHWPOISON): Define if not
	defined.
	* sysdeps/unix/sysv/linux/sparc/bits/errno.h (EHWPOISON):
	Likewise.
	* sysdeps/unix/sysv/linux/sparc/Versions: Add new errlist compat
	entry for 2.16.

I'm confused - why is it suddenly 8 bytes smaller? I would have expected 
8 additional bytes after the change above...

do we need to update sysdeps/unix/sysv/linux/Versions as well?

Andreas
