test: remove test suite

The test suite is now a developed in a separate git repository.
See here:
http://cgit.uclibc-ng.org/cgi/cgit/uclibc-ng-test.git

The test suite should be just like every other software compiled
with the cross-toolchain. In the past strange problems where found
when the test suite got build in the toolchain creation step.

-/* The WRITE_BUFFER_SIZE value needs to be chosen such that if we set
-   the socket send buffer size to '1', a write of this size on that
-   socket will block.
-
-   The Linux kernel imposes a minimum send socket buffer size which
-   has changed over the years.  As of Linux 3.10 the value is:
-
-     2 * (2048 + SKB_DATA_ALIGN(sizeof(struct sk_buff)))
-
-   which is attempting to make sure that with standard MTUs,
-   TCP can always queue up at least 2 full sized packets.
-
-   Furthermore, there is logic in the socket send paths that
-   will allow one more packet (of any size) to be queued up as
-   long as some socket buffer space remains.   Blocking only
-   occurs when we try to queue up a new packet and the send
-   buffer space has already been fully consumed.
-
-   Therefore we must set this value to the largest possible value of
-   the formula above (and since it depends upon the size of "struct
-   sk_buff", it is dependent upon machine word size etc.) plus some
-   slack space.  */
