Alpha cross compiler on x86

[torinfor]

Hey all.  I'm trying to build a gcc cross compiler with the host being 
Linux on x86 and the target being Linux on alpha.  I've built binutils 
fine and have it in place.  I'm configuring gcc as such: 
 
../configure --prefix=/tools --libexecdir=/tools/lib 
--with-local-prefix=/tools --disable-nls --enable-shared 
--enable-languages=c --target=alphapca56-unknown-linux-gnu 
 
which produces this: 
 
loading cache ./config.cache 
checking host system type... i686-pc-linux-gnu 
checking target system type... alphapca56-unknown-linux-gnu 
checking build system type... i686-pc-linux-gnu 
checking for a BSD compatible install... (cached) /usr/bin/install -c 
*** This configuration is not supported in the following 
subdirectories: 
     target-libstdc++-v3 target-libf2c target-libffi target-boehm-gc 
target-zlib target-libjava zlib fastjar target-libobjc 
    (Any other directories should still work fine.)

and then I run: 
 
make BOOT_LDFLAGS="-static" bootstrap 
 
which ends up giving:

Anyone seen this, or have an idea on how to fix it? 
 
Thanks,
