>From Khem Raj <<a href="mailto:raj.khem@gmail.com">raj.khem@gmail.com</a>> in an email to llvm-dev.
Since 5.5 release Linux has dropped sysctl syscall see
<a href="https://github.com/torvalds/linux/commit/61a47c1ad3a4dc6882f01ebdc88138ac62d0df03">https://github.com/torvalds/linux/commit/61a47c1ad3a4dc6882f01ebdc88138ac62d0df03</a>
and subsequently, glibc also dropped the sys/sysctl.h header and
sysctl function. So perhaps tests need to cater for that</pre>
