linux-user/nios2 linux-user/riscv: Clean up header guards Reuse of the same guard symbol in multiple headers is okay as long as they cannot be included together. scripts/clean-header-guards.pl can't tell, so it warns. Since we can avoid guard symbol reuse easily, do so: use guard symbol ${target^^}_${fname^^} for linux-user/$target/$fname, just like we did in commit a9c94277f0..3500385697.

linux-user: Correct definition of stack_t Some platforms used the wrong definition of stack_t where the flags and size fields were swapped or where the flags field had type ulong instead of int. Due to the presence of padding space in the structure and the prevalence of little-endian machines this problem went unnoticed for a long time. The type definitions have been cross-checked with the ones defined in the Linux kernel v5.9, plus some older versions for a few architecture that have been removed and Xilinx's kernel fork for NiosII [1]. The bsd-user headers remain unchanged as I don't know if they are wrong or not.
