Hi,
I don't know much about buildroot, but I gave your two configuration
files a quick look.
From your crosstool-ng configuration file, I saw you have not changed
the default installation path for the generated toolchain:
CT_PREFIX_DIR="${HOME}/x-tools/${CT_TARGET}"
CT_INSTALL_DIR="${CT_PREFIX_DIR}"
These two settings mean the toolchain will be installed in your home
directory: /home/zm02/x-tools/i686-zm-linux-gnu
In buildroot, however, you have not configured this correctly. Instead
you seem to have pointed buildroot to an intermediary toolchain used to
build your final toolchain by crosstool-ng:
BR2_TOOLCHAIN_EXTERNAL_PATH="/home/zm02/development/crosstoo-ng/crosstool-ng-1.18.0/toolChain/.build/i686-zm-linux-gnu/buildtools"
You should use the final toolchain.
