Yes! I think that in my instructions I clearly told that
the $prefix in '--prefix=$prefix' used with binutils and
GCC must be the same! And that GCC doesn't search for the
'$target-<tool>'s although the GCC build scripts will use
just them! Just like humans but GCC isn't some kind of
HAL which behaves just like a human being :(

Expecting a native GCC to search for 'as' and 'ld' and a
cross GCC to search for '$target-as' and '$target-ld' is
a very common misunderstanding, maybe because a native GCC
is usually used via 'gcc' but a cross GCC is used via
'$target-gcc'. Something like: "What I will use, GCC must
use too!", which of course is totally wrong logic :(
