[PATCH] sparc32: Remove unused code.

[David Miller <davem at davemloft dot net>]

longlong.h's sparc code hasn't used the external __udiv_qrnnd function
going back to at least 1998.  It's all done inline in the longlong.h
header file definitions.

The __udiv_qrnnd symbol is not exported from libc, therefore it is
useless and just taking up unnecessary space.

So just remove these files.

Build and 'make check' tested and committed to master.

sparc32: Remove unused code.
