Change subject: crossgcc: Upgrade GCC to 9.2.0
......................................................................

Patch Set 10:

To fix the rest of the build errors, I think setting

GCC_CFLAGS_${TARCH}+=-Wlogical-op -Wno-address-of-packed-member

in util/xcompile/xcompile will ignore this warning for all projects, including Chromium EC and libpayload.

Also, the STACK_SIZE value in soc/cavium/cn81xx/Kconfig needs to be changed from hex to decimal, since -Wstack-usage doesn't recognize hexadecimal numbers anymore.
