[patch] SH: memset fix

[SUGIOKA Toshinobu]

Hi,

On sh[34]-linux, memset function does not work if 2nd argument is negative
and 3rd argument is greater than 12.
for example, memset(ptr, '\xda', 20) sets 0xff instead of 0xda.

Attached patch fixes this problem.

	* sysdeps/sh/memset.S (memset): Correct 2nd argument handling.
