PowerPC: define _CALL_ELF if compiler does not
This patch makes the configure adds -D_CALL_ELF=1 when compiler does not define _CALL_ELF (versions before powerpc64le support). It cleans up compiler warnings on old compiler where _CALL_ELF is not defined on powerpc64(be) builds. It does by add a new config.make variable for configure-deduced CPPFLAGS and accumulate into that (confix-extra-cppflags). It also generalizes libc_extra_cflags so it accumulates in sysdeps configure fragmenets.
