[Felix Singer (Code Review)]

Attention is currently required from: Elyes Haouas, Martin L Roth.

Hello Martin L Roth, build bot (Jenkins),

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

https://review.coreboot.org/c/coreboot/+/83347?usp=email

to look at the new patch set (#5).

Change subject: xcompile: Add -Wextra with temporary exceptions

xcompile: Add -Wextra with temporary exceptions

In order to detect more issues in our code, make GCC more picky by
enabling -Wextra. Disable a couple of warnings turned on by -Wextra
temporarily in order to keep everything compiling and working for now.
The warnings may be enabled step by step later.

Since xcompiles applies to coreboot and libpayload, add Wextra here
instead of the top-level Makefile.mk.
