The eCos build system is looking for GNU tools with an "arm-eabi"
command prefix. You will need to locate and modify the
CYGBLD_GLOBAL_COMMAND_PREFIX option within the eCos Configuration Tool
in order to use a toolchain with an "arm-none-eabi" command prefix. You
will find the option at Configuration -> Global build options -> Global
command prefix within the configuration tree.

I hope this helps...
