Linaro toolchain is a cross-compiler and we use pre-built binaries that are to 
be run on x86 to generate code for ARM. It won't be possible to run it on the 
target (ARM). You'd need to compile the toolchain from sources for ARM. That 
is what Sajesh and Djordje were asking for - to be able to build gcc for the 
target from sources...
