Add g++-multilib build dependency when cross building for ARM.

Add g++-multilib build dependency when cross building for ARM.

We found that this package is needed on 64-bit systems
when cross compiling for ARM due to the requirment that
v8 host binaries be build with -m32 (they must run with
same pointer size as target platform apparently).

This should avoid the need for any extra package installation on the arm
buildbots.

Are we sure these AREN'T used? Or are these implicit deps of g++-multilib?

I'm pretty sure we don't need any gcc-4.5 packages.  The cross tools in precise
are 4.6.  I can't see why the 4.5 packages were ever on the list.  I've removed
them from my local system an build chrome for ARM without them.

The g++-multilib dependency is for building the x86 host binaries not the arm
ones, so its unrelated.
