* sysdeps/sparc/sparc64/Makefile: Add align-cpy rule.
* sysdeps/sparc/sparc64/align-cpy.S: New.
* sysdeps/sparc/sparc64/memcpy.S (__align_cpy_1, __align_cpy_2,
__align_cpy_4, __align_cpy_8, __align_cpy_16): Remove.
* sysdeps/sparc/sparc64/sparcv9b/memcpy.S (__align_cpy_1,
__align_cpy_2, __align_cpy_4, __align_cpy_8, __align_cpy_16):
Remove.
* sysdeps/sparc/sparc64/sparcv9v/memcpy.S (__align_cpy_1,
__align_cpy_2, __align_cpy_4, __align_cpy_8, __align_cpy_16):
Remove.
* sysdeps/sparc/sparc64/sparcv9v2/memcpy.S (__align_cpy_1,
__align_cpy_2, __align_cpy_4, __align_cpy_8, __align_cpy_16):
Remove.
