sparc: remove sparc64/sparcv9 code

The sparc64/sparcv9 code is incomplete. Furthermore there is
no real embedded hardware for sparc64 available, so better remove
it until someone comes up with a complete port.

-	   ((xword - 0x0101010101010101) & 0x8080808080808080) test
-	   to find out if any byte in xword could be zero. This is fast, but
-	   also gives false alarm for any byte in range 0x81-0xff. It does
-	   not matter for correctness, as if this test tells us there could
-	   be some zero byte, we check it byte by byte, but if bytes with
-	   high bits set are common in the strings, then this will give poor
-	   performance. You can #define EIGHTBIT_NOT_RARE and the algorithm
-	   will use one tick slower, but more precise test
-	   ((xword - 0x0101010101010101) & (~xword) & 0x8080808080808080),
-	   which does not give any false alarms (but if some bits are set,
-	   one cannot assume from it which bytes are zero and which are not).
-	   It is yet to be measured, what is the correct default for glibc
-	   in these days for an average user.
