Redefine dynamic linker for aarch64 from /lib to /lib64.
BASELIB of aarch64 has to be defined with 'lib64', then linker file

update it here too.
hmmm since the ldso name is different it can still live in /lib
and there will be ilp32 version ldso multilib as well later. can we
keep
ldso in /lib ?
I thought the upstream definition (managed by ARM Ltd, and Linaro)
for the ld.so
had changed a few months back so that /lib64 was the 'standard'
location for the
ldso. Perhaps I'm mistaken?
I did some research and I'm confused.. aarch64 is screwed up by
consensus apparently..
Dynamic libraries live in /lib64, and the dynamic linker in /lib.. Whee!
So ya, this patch isn't correct.. the dynamic linker needs to stay in
/lib. (Nothing says you can't sym/hardlink to lib64.. but it has to
refer to in in /lib for the ABI conformance.)
OK. Keep dynamic linker in /lib and change libraries directory from
/lib64 to /lib.
