execline: using cd in a script

[yianiris via skaware]

As I discovered execline cd replaces the linux utility in a system and
produces peculiar results

On console cd seems to be perfect as expected, on script #!/bin/sh
when changing to a directory in a mounted partition it fails, while
normal cd works as if it is on a single partition.

Is this something known, is therre a way to compile fixing this, does it
relate to glibc/gcc upgrades ..?
