xcompile: Apply -Wextra with temporary exceptions to GCC

Browse Source 
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.
