Build on Neoverse V2 is failing with:

MUST-v1.11.2/externals/GTI/externals/PnMPI/src/pnmpi/wrapper.c:1046:32: error: operand of type 'va_list' (aka '__builtin_va_list') where arithmetic or pointer type is required
 1046 |           start = (TRANSTYPE *)va_alist;
      |                                ^~~~~~~~
1 error generated.

This is the code around the failure:

      size = va_arg(va_alist, int);
      if (type & PNMPI_PCONTROL_VARGorPTR)
        {
          /* PTR */
          start = (TRANSTYPE *)(va_arg(va_alist, void *));
        }
      else
        {
          start = (TRANSTYPE *)va_alist;
        }
      leni = (size + sizeof(TRANSTYPE) - 1) / sizeof(TRANSTYPE);

---

This general failure seems to be due to how varadic arguments are handled on aarch64. A similar small reproducer can trigger a build failure on aarch64 with GCC / LLVM but not on x86.
