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.
