    ksan: Build sanitizer runtimes without stack-smashing protection
    
    On arm64 with per-thread stack canaries enabled (the PERTHREAD_SSP
    option), the compiler may load curthread->td_md.md_canary in function
    prologues.  This is not safe in data_abort(); see commit 2c10be9e06d4.
    Thus, sanitizer runtimes must also avoid accessing the current thread's
    canary.
    
    Since SSP has limited utility in sanitizer runtimes, simply disable it
    unconditionally to avoid unpleasant surprises in the future.
