RISC-V: Use 64-bit-time syscall numbers with the 32-bit port
sysdep.h redefines only the syscall where the generic implementation
still does not have actual 64-bit time_t support:
/* Workarounds for generic code needing to handle 64-bit time_t. */
/* Fix sysdeps/unix/sysv/linux/clock_getcpuclockid.c. */
#define __NR_clock_getres __NR_clock_getres_time64
/* Fix sysdeps/nptl/lowlevellock-futex.h. */
#define __NR_futex __NR_futex_time64
[...]
This patch also adds a comment that it is a workaround to handle 64-bit
time_t and on each #define comment for which implementation it intends
to.
