build stuck: rtems-4.10.2, arm-elf, nds

[Matt Wette]

I'm looking for hints.  

I built tools, then configure rtems-4.10.2 for --target=arm-elf, then make RTEMS_BSP=nds
It fails in configure for arm/nds, saying compiler cannot generate executables.  But I verified:

localhost$ cat zzz.c
int
main ()
{
  ;
  return 0;
}
localhost$ vi zzz.c
localhost$ cat zzz.c
int main () {
  ;
  return 0;
}
localhost$ arm-elf-gcc zzz.c
localhost$ file a.out
a.out: ELF 32-bit LSB executable, ARM, version 1, statically linked, not stripped
localhost$
