Hi,
The compiler and debugger are provided by Linaro as 32-bit programs; you should then install the 32-bit versions of the required libraries.
I know this is inconvenient, but we prefer to stick to the Linaro-provided compiler distribution as it is validated before release by Linaro, with an extensive test suite, something we could not do if we recompile it for 64-bit. So, as long as Linaro is only providing 332-bit Linux executables, you must install the needed 32-bit libraries.
