Yes.  The attached patches make --target work.
For the moment specifying --target at configure time has no effect:
the value set by the configure script into $target is not used.
Currently we are using the value set by the configure scripts in
$host to build the target toolchain, and this is IMHO the wrong
thing to do.

With these two patches, we take the value from $target and use it
to build the default target toolchain: so when I say
configure --target=arm-none-linux-gnueabi
I get a clang that produces ARM assembly by default
(without these two patches, I currently get x86_64 assembly as
the host is x86_64).

Thanks,
Sebastian
