ubsan: remove redundant -Wno-maybe-uninitialized
Patch series "Clean up UBSAN Makefile", v2. 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, disable UBSAN_TRAP under COMPILE_TEST for wider build coverage, and expand the libusan tests. This patch (of 7): In commit 78a5255ffb6a ("Stop the ad-hoc games with -Wno-maybe-initialized") -Wmaybe-uninitialized was disabled globally, so keeping the disabling logic here too doesn't make sense.
