[PATCH] Updates on busybox POSIX compliance

[David Krakov]

Hi,

Table can be updated only manually - documenting differences between
POSIX and busybox behaviour on options that do exist.
It can serve as a mini-TODO file.
The only easy way I see to go with tests is to check for full
compliance by comparing with GNU (which is not strictly compliant
itself).

I ran the test suite - there are some FAILs:
 * Is it up to date?
 * I've seen some tests compare with GNU tools output - does it
require a specific version of GNU utilities?

Though there are tests that can be used for this objective, the test
suite is lacking a simple way to mark existing tests with some kind of
a flag like POSIXTEST. How do you propose to do that?

P.S
attached `runtest -v` stdout and stderr.
