config KASAN_STACK_ENABLE

help
The LLVM stack address sanitizer has a know problem that
causes excessive stack usage in a lot of functions, see
https://bugs.llvm.org/show_bug.cgi?id=38809
Disabling asan-stack makes it safe to run kernels build
with clang-8 with KASAN enabled, though it loses some of
the functionality.
This feature is always disabled when compile-testing with clang-8
or earlier to avoid cluttering the output in stack overflow
warnings, but clang-8 users can still enable it for builds without
CONFIG_COMPILE_TEST. On gcc and later clang versions it is
assumed to always be safe to use and enabled by default.
