Building zephyr for xtensa with gcc requires additional include paths and additional library (libhal). Add xtensa sysroot and include paths to CFLAGS when building for xtensa. The root Makefile then does the right thing adding these parameters to KBUILD_CFLAGS and KBUILD_ASFLAGS. Add xtensa libhal to the TOOLCHAIN_LIBS_xtensa. Modify TOOLICHAIN_LIBS to include arch-specific libraries. Seems that it would be nice to have TOOLCHAIN_CFLAGS_$(ARCH) with the same behavior as TOOLCHAIN_LIBS_$(ARCH). It also seems that the SYSROOT definition doesn't have to be restricted to MAKEFILE_TOOLCHAIN_DO_PASS2.
