[coreboot-gerrit] Change in ...coreboot[master]: build system: Add various compiler flags that enable warnings on UB

[Patrick Georgi (Code Review)]

Hello Martin Roth,

I'd like you to reexamine a change. Please visit

https://review.coreboot.org/c/coreboot/+/32814

to look at the new patch set (#2).

Change subject: build system: Add various compiler flags that enable warnings on UB
......................................................................

build system: Add various compiler flags that enable warnings on UB

Some types of Undefined Behavior can be determined statically at compile
time and gcc now has a set of flags that make it emit warnings in that
case instead of doing the __builtin_trap() / optimize / UD2-opcode dance
that silently breaks the resulting binary.

BUG=chromium:958270
BRANCH=none
TEST=abuild passes (probably not)
