I downloaded the aarch64 binaries to  a ubuntu machine:

  wink@ssi-primary:~$ uname -a
  Linux ssi-primary 3.5.0-21-generic #32-Ubuntu SMP Tue Dec 11 18:51:59 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux


And when I try to run gcc-4.7.3:

  wink@ssi-primary:~$ ls -al ~/aarch64-toolchain/gcc-linaro-aarch64-linux-gnu-4.7+bzr115029-20121015+bzr2506_linux/bin/aarch64-linux-gnu-gcc-4.7.3

I get a file not found:

  wink@ssi-primary:~$ strace /home/wink/aarch64-toolchain/gcc-linaro-aarch64-linux-gnu-4.7+bzr115029-20121015+bzr2506_linux/bin/aarch64-linux-gnu-gcc-4.7.3 -v

I must have done something real stupid, any help appreciated.
