[DistroKit] Y2038 support broken on MIPS

[DistroKit] Y2038 support broken on MIPS

[Robert Schwebel]

Hi,

I've today updated DistroKit to ptxdist-2023.07.1, and I tried the new
PTXCONF_GLIBC_Y2038 feature. It seems to work everywhere but on MIPS.
In qemu, it stops here:

rsc@dude05:~/work/DistroKit$ configs/platform-mips/run

Changing the config option makes it boot again.

If someone wants to debug it, go ahead :-)

The next branch with my latest patches seems to work in a y2038 mode.
