Carlos Santos 6732d952d0 package/busybox: fix build with musl 1.2.0
Busybox 1.31.1 fails to build with musl 1.2.0 due to the direct use of
__NR_clock_gettime. Pull four patches already applied upstream to fix
the problem.

The patches were rebased to version 1.31.1 to minimize the change, since
the original ones depended on a previous commit which is not worthwhile
to pick.

Fixes:

Subject: [PATCH] time: Use 64 prefix syscall if we have to
Some 32-bit architectures no longer have the 32-bit time_t syscalls.
Instead they have suffixed syscalls that returns a 64-bit time_t. 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. This avoids us have to
deal with converting between 64-bit and 32-bit values. There are
currently no architectures where this is the case.
