The symbol is defined in kernel's arch/Kconfig with 'default !64BIT || COMPAT'. Introduce Config.in.compat which has the symbol default to y unless a known 64bit ADK_TARGET_ARCH is enabled. Drop the symbol from all target/*/kernel/* for which the default applies.
On 64bit systems, enabling this symbol is probably useful to provide comaptibility towards 32bit user space. Not sure if this is a possible choice in OpenADK, but just in case the symbol was not removed from:
- target/aarch64/kernel/raspberry-pi4-64 - target/mips64/kernel/qemu-mips64 - target/riscv64/kernel/qemu-riscv64
Another case is targets explicitly having the symbol disabled, namely kvx. Given that the two kernel configs in question are full copies of the kernel-generated one, they are likely not a deliberate choice and thus removed as well.

What C library you are using? Nowadays glibc/uClibc-ng and musl have 64 Bit time_t on all supported 32 Bit architectures with a recent enough kernel (=>5.1.0).
I think using this kernel symbol is only required for C libraries not having 64 Bit time_t. So we could remove the symbol entirely in OpenADK.
What you think?

I checked this on my Cubox-i (ARM 32 Bit) and your patch is valid. It seems this kernel symbol is even required for time64 enabled userland.

While your point is valid regarding 64bit time_t, the problem here seems to be io_getevents syscall which expects a 32bit time_t in parameters. I guess this can't change due for compatibility reasons and one had to introduce a new syscall which accepts the larger time_t. Or is this just covered by the libc wrappers?
I checked this on my Cubox-i (ARM 32 Bit) and your patch is valid. It seems this kernel symbol is even required for time64 enabled userland.
Thanks for validating!
BTW: Does gcc-14 work for you? It built fine for me but I got compile errors building packages. Went with gcc-12 for now.

I use the default gcc-13 for now, which compiles all packages I use fine. Yes, gcc-14 will break a lot of packages.
Do you have any issue with gcc-13?

While your point is valid regarding 64bit time_t, the problem here seems to be io_getevents syscall which expects a 32bit time_t in parameters. I guess this can't change due for compatibility reasons and one had to introduce a new syscall which accepts the larger time_t. Or is this just covered by the libc wrappers?
Good question, I don't know :-/
I checked this on my Cubox-i (ARM 32 Bit) and your patch is valid. It seems this kernel symbol is even required for time64 enabled userland.
Thanks for validating!
BTW: Does gcc-14 work for you? It built fine for me but I got compile errors building packages. Went with gcc-12 for now.
I use the default gcc-13 for now, which compiles all packages I use fine. Yes, gcc-14 will break a lot of packages.
Do you have any issue with gcc-13?

What C library you are using? Nowadays glibc/uClibc-ng and musl have 64 Bit time_t on all supported 32 Bit architectures with a recent enough kernel (=>5.1.0).

I think using this kernel symbol is only required for C libraries not having 64 Bit time_t. So we could remove the symbol entirely in OpenADK.
