[PATCH] riscv: Add big-endian support to string-fzi.h.

[Adhemerval Zanella Netto]

What about Linux support? Last time I checked there is no option for
CPU_BIG_ENDIAN on arch/riscv and I recall that Linus was not very
enthusiastic about it.

Also, the pull request also states that BE support is not yet complete
on gcc [1], is that the case?
