This is not possible with the current design of the xtensa toolchain port.
There's an effort to make switching between the core configurations easy
(without the whole toolchain rebuild:
 https://github.com/jcmvbkbc/xtensa-dynconfig
 https://github.com/jcmvbkbc/gcc-xtensa/tree/xtensa-dynconfig
 https://github.com/jcmvbkbc/binutils-gdb-xtensa/tree/xtensa-plugin-env ),
but it still involves building plugins for the parts of the toolchain
for each new xtensa core.
