Subject: [PATCH 0/4] Clean up UBSAN Makefile

Hi,

This series attempts to address the issues seen with UBSAN's object-size
sanitizer causing problems under GCC. In the process, the Kconfig and
Makefile are refactored to do all the cc-option calls in the Kconfig.
Additionally start to detangle -Wno-maybe-uninitialized, and disable
UBSAN_TRAP under COMPILE_TEST for wider build coverage.

Thanks!

-Kees
