Seems like saving the intermediate crosstool bits won't be that useful?

This appears to trigger some compiler bugs. Let's see if disabling
this option generates a working toolchain.

gcc: Add xtensa core-isa.h to gcc overlays
11b78ba 
This file depends upon the architecture configuration and is generated
along with the remaining compiler configuration bits. While gcc
doesn't use it, delivering it with gcc avoids needing to customize the
C libraries and simplifies the SDK. It also makes using the toolchain
for other C library development, like picolibc CI, possible.

binutils: Disable warning about RWX segments by default

Zephyr can add an option to re-enable them, but we want to disable

make these useful.
