I think I have to agree with Lei Sun.  My armnommu platform was also
having argv and envp problems after I switched uclibc from 0.9.26 to
0.9.28.  I don't know much about assembly codes, so I don't know what goes
wrong in crt1.S.  But I am sure that the problem is in that part.

For those who do not want to recompile your toolchain right now, I think
this should work for the moment:

int main(int argc, char *argv[], char *envp[]) {
  int i;
  argv = &argv[2];
  for (i=0; NULL != argv[i]; i++);
  envp = &argv[i+1];
  ...
}
