"No rule to make target" error when building gcc

[Kevin Wilson]

Hello,
I am trying to build a 32 bit gcc compiler on a 64 bit machine (Linux).

What I did is this:

Untarred gcc to gcc-4.1.2-20070925 folder (I used the gcc sources of
gcc-4.1.2-33.src.rpm)

create an empty build folder. from there I ran:

../gcc-4.1.2-20070925/configure --prefix=/work/tools/fc8_i386/gcc
  --enable-threads=posix --enable-languages=c --target=i686-linux
	
After some time it stops with this error:
make[2]: *** No rule to make target
`/work/tools/fc8_i386/gcc/bin/i686-linux-as', needed by `stamp-as'.
Stop.


Any ideas why ?
full log of the error is below:
