Using '--with-gnu-as --with-gnu-ld' is obligatory with this target!

The native DEC 'ld' would require this utility. That a cross GCC will
be produced doesn't have any influence to the defaults (=native) for
'as' and 'ld'...

Please consult the 'gcc/config.gcc' settings for the available targets!
The gcc-4.5.2 one will show the influence of '--with-gnu-*'... in the
alpha case...
