Hi Linus,

I use the following scripts to build cross-compiler for xtensa:
https://github.com/jcmvbkbc/xtensa-toolchain-build

You'd need to download binutils/gcc/gdb source tarballs with versions
specified in config and then run

$ ./prepare.sh fsf && ./fixup-gdb.sh && ./build.sh fsf


FWIW I see that the issue is caused by building drivers/gpio/devres.c
with CONFIG_GPIOLIB=n. Should I just turn GPIO_DEVRES off too?

Thanks.
