Why do we need to export the __libc_aligned_alloc symbol?  That doesn't
seem to be right.  We should simply change the behavior of the existing
aligned_alloc symbol.

If you do not want to change behavior for existing binaries (why?), you
should still export a new aligned_alloc@@GLIBC_2.38 symbol (no __libc_
prefix).
