RISC-V: Update syscall list for 32-bit support.

[Qemu-devel] [PATCH] RISC-V: Update syscall list for 32-bit support.

Posted by Jim Wilson 6 years, 4 months ago

32-bit RISC-V uses _llseek instead of lseek as syscall number 62.
Update syscall list from open-embedded build, primarily because
32-bit RISC-V requires statx support.

Tested with cross gcc testsuite runs for rv32 and rv64, with the
pending statx patch also applied.
