re PR bootstrap/50237 (bootstrap comparison failure for libcpp/lex.o) 

	PR bootstrap/50237
	* config/initfini-array.h: Guard content of the header
	with #ifdef HAVE_INITFINI_ARRAY.
	* configure.ac: Move gcc_AC_INITFINI_ARRAY much later into the file.
	Add initfini-array.h to tm_file here.
	* acinclude.m4 (gcc_AC_INITFINI_ARRAY): For non-ia64 do a linker
	test.
	* config.gcc: Don't add initfini-array.h to tm_file here.
	* configure: Regenerated.
