 Turned out my test kernel had no options PAX_MPROTECT (accident in the config
 file), so the elf note disabling pax mprotect got lost in a slightly
 non obvious pax_setup_elf_flags() macro that does nothing.
 
 Not sure if we should consider the silent enforcement a bug - it is not obvious
 to me where it happens.
 
 But for the issue at hand: solved by fixing the kernel config.
