If +the architecture doesn't have the non-suffixed syscall and is using a +64-bit time_t let's use the suffixed syscall instead. + +This fixes build issues when building for RISC-V 32-bit with 5.1+ kernel +headers. + +If an architecture only supports the suffixed syscalls, but is still +using a 32-bit time_t report a compilation error.
