[musl] [PATCH] riscv: Fix setjmp assembly when compiling for ilp32f/lp64f.

[musl] [PATCH] riscv: Fix setjmp assembly when compiling for ilp32f/lp64f.

[Alex Rønne Petersen]

To keep things simple, I just changed the instruction mnemonics appropriately,
rather than adding complexity by changing the buffer size/offsets based on ABI.
