[Patch ARM] Fix definition of MALLOC_ABI_ALIGNMENT.

[Ramana Radhakrishnan]

Hi,

This sets MALLOC_ABI_ALIGNMENT to 64 bits on ARM which should be safe
on all AAPCS implementations given that this is a requirement on our
alignment specifiers. I would expect this to be true for most modern
malloc implementations on AAPCS targets -

Ok ?
