* sysdeps/gnu/errlist-compat.awk: Don't bail if Versions gives a count
	higher than ERR_MAX reports.  Instead, emit a #define ERR_MAX.
	* sysdeps/gnu/Makefile ($(objpfx)errlist-compat.h): New target.
	(generated): Add errlist-compat.h.
	* sysdeps/gnu/errlist.awk: Make output #include <errlist-compat.h> to
	define ERR_MAX and use that for table size.
