[seL4] seL4_Fault_t and friends seems to be missing in user libsel4

Hello,

if I compile and link seL4 5.2.0

ARCH=x86 PLAT=pc99 SEL4_ARCH=x86_64 make

and I finally try to use the generated syscall/libsel4 headers, the compiler complains about missing seL4_Fault types and functions in

libsel4/sel4_arch_include/x86_64/sel4/sel4_arch/faults.h

like

seL4_Fault_t seL4_Fault_tag seL4_Fault_VMFault_new

and a lot more.

These structs and functions seems to be generated only for the kernel side, e.g. in kernel_final.c they show up, but there are no traces of them on the user level side.

Do I just miss a configuration option ?

Thanks,
