The
xtools
toolchain variant (aka. Crosstool-NG) was originally introduced to be used with the Crosstool-NG-based Zephyr SDK toolchains (i.e. sdk-ng).This is no longer necessary because the current Zephyr SDK (sdk-ng) already has its own
zephyr
toolchain variant, which fully replaces thextools
toolchain variant, and thextools
toolchain variant serves no purpose at all.Related to #51332
