Hi Luya,

Clang does not support the -fstack-clash-protection flag. We used to silently ignore that flag but it's no longer the case.
Why are you using clang to compile the package? The safe step is to use gcc, ot if clang is needed, to strip -fstack-clash-protection
from the flags passed to clang, but that's not future-proof (clang may end up supporting that flag).

Hope it helps,

Serge
