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.
