Avoid trailing whitespace in sysdeps/gnu/errlist.c

["Joseph S. Myers" <joseph at codesourcery dot com>]

This patch avoids trailing whitespace in the generated file
sysdeps/gnu/errlist.c by adjusting the generator errlist.awk not to
generate it.  Tested x86_64.

2013-06-06  Joseph Myers  <joseph@codesourcery.com>

	* sysdeps/gnu/errlist.awk: Do not generate space at end of
	otherwise empty TRANS lines.
	* sysdeps/gnu/errlist.c: Regenerated.
