powerpc: Remove HAVE_ASM_GLOBAL_DOT_NAME define
With AIX port deprecated there is no need to check/define HAVE_ASM_GLOBAL_DOT_NAME anymore since the current minimum binutils supported (2.22) does not emit global symbol with dot. This patch removes all the HAVE_ASM_GLOBAL_DOT_NAME definition and checks for powerpc64 port.
