Comment 13 for bug 1081162

Fixed stat, statfs, symlinkat issues and set up the mksh test shell. Now manual testing passes for all, dash and gzip seems to be working fine but there are 5 failures out of the 436 mksh tests. So I am debugging them one by one.

I noticed compilation errors while building mksh for klibc, but dont know if I am OK with them or not. Now I am just assuming that they are probably OK and debugging the failures. The 5 mksh test failures are as follows. If anyone has any idea, please share. Thanks.
