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.

-   This version is developed using the same algorithm as the fast C
-   version which carries the following introduction:
-   Based on strlen implementation by Torbjorn Granlund (tege@sics.se),
-   with help from Dan Sahlin (dan@sics.se) and
-   commentary by Jim Blandy (jimb@ai.mit.edu);
-   adaptation to memchr suggested by Dick Karpinski (dick@cca.ucsf.edu),
-   and implemented by Roland McGrath (roland@ai.mit.edu).

-	   ((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.
