OK I am assuming that the external toolchain you are trying to plugin
is a uclibc-based toolchain
please note that if external toolchain is constructed with other
libraries (e.g. glibc eglibc) then it may have
problems building a uclibc based system. So make sure that external
toolchain was configured with uclibc
secondly the TARGET_OS for arm/uclibc systems with EABI is
linux-uclibceabi and not linux-uclibc
if you use linux-uclibc it will use Old ABI which may not be what the
external toolchain is configured for.
