[Christophe Leroy]

This patch adds a test for testing the new assembly strlen() for PPC32

Signed-off-by: Christophe Leroy <christophe.leroy@xxxxxx>
---
 v8: removed defines in ppc_asm.h that were added in v6 (not used anymore since v7) ; added missing link to strlen_32.S
 v7: reduced the scope to PPC32
 v6: added additional necessary defines in ppc_asm.h
 v5: no change
 v4: new
