ARM Multilibs with --with-mode=thumb

[gnubie gnubie]

Hi Terry,

Thank you very much.  It was this macro that I had managed to miss:
>  #ifndef MULTILIB_DEFAULTS
>  #define MULTILIB_DEFAULTS \
> -  { "marm", "mlittle-endian", "mfloat-abi=soft",
> "mno-thumb-interwork", "fno-leading-underscore" }
> +  { "mthumb", "mlittle-endian", "mfloat-abi=soft",
> "mno-thumb-interwork", "fno-leading-underscore" }
>  #endif

Yours,
Carlos
