latest version of php configure fails to compile program that uses 'fopen'

[MikeFultonDev]

configure generates the C test:
conftest.c

#include <stdio.h>
#include <stdlib.h>

typedef union _mm_align_test {
  void *ptr;
  double dbl;
  long lng;
} mm_align_test;

#if (defined (__GNUC__) && __GNUC__ >= 2)
#define ZEND_MM_ALIGNMENT (__alignof__ (mm_align_test))
#else
#define ZEND_MM_ALIGNMENT (sizeof(mm_align_test))
#endif

int main()
{
  size_t i = ZEND_MM_ALIGNMENT;
  int zeros = 0;
  FILE *fp;

  while (i & ~0x1) {
    zeros++;
    i = i >> 1;
  }

  fp = fopen("conftest.zend", "w");
  fprintf(fp, "(size_t)%zu (size_t)%d %d\n", ZEND_MM_ALIGNMENT, zeros, ZEND_MM_ALIGNMENT < 4);
  fclose(fp);

  return 0;
}

and then tries to compile the code. Here is a script that is the same as the compile:
compalign

#!/bin/sh

clang -o conftest -fno-common -Wstrict-prototypes -Wall -Wextra -Wno-strict-aliasing -Wno-unused-parameter -Wno-sign-compare -fzos-le-char-mode=ascii -std=gnu11 -mnocsect -fno-short-enums -fno-builtin-malloc -fno-builtin-calloc -fno-builtin-realloc -mzos-target=zosv2r4 -O3  -I/home/fultonm/zopen/usr/local/zopen/ncurses/ncurses-6.3.20231105_110138.zos/include -I/home/fultonm/zopen/usr/local/zopen/libiconv/libiconv-1.17.20231019_173613.zos/include -I/home/fultonm/zopen/usr/local/zopen/libxml2/libxml2-2.9.12.20231101_144831.zos/include -I/home/fultonm/zopen/usr/local/zopen/libxml2/libxml2-2.9.12.20231101_144831.zos/include/libxml2 -I/home/fultonm/zopen/usr/local/zopen/sqlite/sqlite-autoconf-3420000.20230913_200825.zos/include -isystem /home/fultonm/zopen/usr/local/zopen/zoslib/zoslib-zopen.20231019_211406.zos/include -include /home/fultonm/zopen/usr/local/zopen/zoslib/zoslib-zopen.20231019_211406.zos/include/zos-v2r5-symbolfixes.h -fvisibility=hidden -DNSIG=42 -D_XOPEN_SOURCE=600 -D_ALL_SOURCE -D_OPEN_SYS_FILE_EXT=1 -D_AE_BIMODAL=1 -D_ENHANCED_ASCII_EXT=0xFFFFFFFF  -DZOSLIB_OVERRIDE_CLIB=1 -D_GNU_SOURCE  conftest.c

This fails to link:

 IEW2456E 9207 SYMBOL __fopen_ascii UNRESOLVED.  MEMBER COULD NOT BE INCLUDED
          FROM THE DESIGNATED CALL LIBRARY.
 IEW2665S 40FF MODULE *NULL*  IS NON-EXECUTABLE AND WAS NOT SAVED BECAUSE
          STORENX=NEVER.
IEW5033 The binder ended with return code 12.
clang-14: error: linker command failed with exit code 12 (use -v to see invocation)

@IgorTodorovskiIBM is this a known limitation is zoslib? Is there an issue I should reference there?
