Solve the y2038 problem for powerpc
AKA Make time_t 64 bits on powerpc(32). PowerPC currently (until now) was one of two architectures with a 32-bit time_t on 32-bit archs (the other being i386). This is an ABI breakage, so all ports, and all local binaries, *must* be recompiled. Tested by: andreast, others MFC after: Never Relnotes: Yes

20170625:
|
||||
The FreeBSD/powerpc platform now uses a 64-bit type for time_t. This is
|
||||
a very major ABI incompatible change, so users of FreeBSD/powerpc must
|
||||
be careful when performing source upgrades. It is best to run
|
||||
'make installworld' from an alternate root system, either a live
|
||||
CD/memory stick, or a temporary root partition. Additionally, all ports
|
||||
must be recompiled. powerpc64 is largely unaffected, except in the case
|
||||
of 32-bit compatibility. All 32-bit binaries will be affected.
|
||||

||||
20170623:
|
||||
Forward compatibility for the "ino64" project have been committed. This
|
||||
will allow most new binaries to run on older kernels in a limited
