On 32-bit systems, musl only defines SYS_timer_settime32 not
SYS_timer_settime. This causes the following compilation error:
os_linux.go:251:30: error: reference to undefined name
'_SYS_timer_settime'
251 | return int32(syscall(_SYS_timer_settime,
uintptr(timerid), uintptr(flags), uintptr(unsafe.Pointer(new)),
uintptr(unsafe.Pointer(old)), 0, 0))
| ^
This commit fixes this error by "aliasing" SYS_timer_settime to
SYS_timer_settime32 if the latter is defined. This is also what
musl does internally [1].
