Cannot build cross gcc for m68k under Linux

[Wolfgang Fritz <wolfgang dot fritz at datentechnik dot com>]

Hi,

I'm trying to build a cross development toolchain for m68k processors on
a Linux host.
Up to now I've not been able to generate the cross compiler.

What I did:

1. Downloaded sources:
binutils-2.11.2.tar.gz  gcc-2.95.3.tar.gz  newlib-1.9.0.tar.gz

2. Did some Web search and RTFM

3. Found some failing instructions, confusing (outdated) FAQs which
leaded to:

4. Failed to build the cross compiler

5. Did more searches on the Web and found this mailing list

6. Downloaded the complete 2001 archive into netscape and tried to find
some hints

7. Found the FAQ and compile script on http://crossgcc.billgatliff.com

8. Updated binutils version number in the compile script

9. Ran the script.

Results:
binutils were built and installed successfully.
core-gcc was built successfully.
newlib was built without complaints (but see below)
gcc build failed with error messages:

make[2]: Entering directory
`/data4/home/wfr/m68k/build-gcc/m68k-coff/libiberty'
make[2]: *** No targets specified and no makefile found.  Stop.
make[2]: Leaving directory
`/data4/home/wfr/m68k/build-gcc/m68k-coff/libiberty'
make[1]: *** [../libiberty/libiberty.a] Error 2
make[1]: Leaving directory
`/data4/home/wfr/m68k/build-gcc/m68k-coff/libstdc++'
make: *** [all-target-libstdc++] Error 2

I know from the list that this is a standard error case, but I didn't
see a solution, so I did some more studies:

I found the following standard message earlier in the log:
checking whether the C compiler (/data4/home/wfr/m68k/build-gcc/gcc/xgcc
-B/data4/home/wfr/m68k/build-gcc/gcc/
-B/data4/home/wfr/cross/m68k-coff/bin/ -g -O2 ) works... no
configure: error: installation or configuration problem: C compiler
cannot create executables.

This is a standard error case too, but...

I looked into the config.log in the libiberty directory and found the
following:

 configure:1749: checking whether the C compiler

configure: failed program was:

#line 1760 "configure"
#include "confdefs.h"

main(){return(0);}

So there must be something wrong with the libraries?? Where are these
missing symbols usually defined?

I cannot see a missing path or something, the libraries seem to be
there, but obviously there is something missing. I will continue to
investigate that problem on my own, but would be very glad for a hint or
a solution.
