- Use ustringp for the location of the argv and environment strings and allow destp to travel further down the stack for the stackgap and auxv regions. - Update the Linux copyout_strings variants to move destp down the stack as was done for the native ABIs in r263349. - Stop allocating a space for a stack gap in the Linux ABIs. This used to hold translated system call arguments, but hasn't been used since r159992.
