Remove stddef.h configure test. 

There is a configure test "for libc-friendly stddef.h", which sets a
makefile variable stddef.h that appears to be nowhere used.  It
appears the uses of this variable were removed by:

Tue Feb 21 00:10:50 1995  Roland McGrath  <roland@churchy.gnu.ai.mit.edu>

        * Makefile (headers): Remove $(stddef.h).
        * Makeconfig (stddef.h): Variable removed; now require gcc version
        >= 2.2.
        * stddef.h: File removed.

(having been added by

Wed May 26 14:44:19 1993  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * configure.in (autoconf checks): Add new check for a
        libc-friendly stddef.h.

so the test was of use for less than two years, before being obsolete
for over 20 years).  This patch removes the test.

Tested for x86_64 and x86 (testsuite, and that installed shared
libraries are unchanged by the patch).

	* configure.ac (libc_cv_friendly_stddef): Remove configure test.
	* configure: Regenerated.
