linux: disable attribute alias with gcc >= 8.1
gcc-8 started warning about function aliases that have a non-matching
prototype. This seems rather useful in general, but it causes tons of
warnings in the Linux kernel, where we rely on abusing those aliases
for system call entry points, in order to sanitze the arguments passed
from user space in registers.
See https://gcc.gnu.org/bugzilla/show_bug.cgi?id=82435
Disable the attribute-alias warning introduced by gcc-8 by adding
-Wno-attribute-alias to KCFLAGS.
