Several multiarch/biarch fixes

Browse Source 
* Add multiarch directories for arm and i386
* Fix detection of biarch: /lib64/ld-linux-x86-64.so.2 is mandated by
  ABI and is thus always present, even if there is no biarch
* Define CONFIG_LDDIR directly with the right value in case of multiarch
  instead of defining it to /lib and then redifining it.
