How did you configured and built gcc?

It seems that it uses the target compiler (arm) to create the host gcc tools.
gengenrtl and the like should be compiled by the native compiler.  Not the cross compiler.

I can't tell much about arm-linux but to create the 68HC11 cross compiler
I use the following:

1/ I make sure that the native Ada compiler is in my path
    (I'm using gcc 3.3, compiled with --enable-languages=c,c++,ada)
    Check this with 'gcc -v', you should see something like:

/usr/local/3.3/bin/gcc -v
Reading specs from /usr/local/3.3/lib/gcc-lib/i686-pc-linux-gnu/3.3/specs
Configured with: ../gcc-3.3/configure --enable-languages=c,c++,ada --prefix=/usr/local/3.3
Thread model: posix
gcc version 3.3

2/ I make sure that the target (68HC11) binutils are available in my path too

3/ Configure the cross compiler:

    ./configure --target=m6811-elf --enable-languages=c,ada --prefix=m6811-elf-

4/ Build the stuff

    make
  or
    make bootstrap

  [Note: I don't remember if 'make bootstrap' works for building a cross compiler;
         It is absolutely mandatory when building a native compiler]

For an arm, it should be fairly similar,

Hope this helps,
	Stephane
