Any success building cross ARM gcc on HPUX?

[Klaus Pedersen <klaus dot k dot pedersen at nokia dot com>]

Hi,

I have for some time tried to build a ARM cross compiler for HPUX 11.
(uname: HP-UX B.11.00 A 9000/785 2014470784)

But I haven't had any success yet. Please let me hear if you have had
success doing that.

For the record, I have successfully build the same most current 
snapshot on both SunOS 5.6 and Linux (Mandrake 8.1).

I used this configure:

../gcc-20011203/configure \
     --prefix=/opt/arm-elf-gcc --target=arm-elf --nfp \
     --enable-languages=c,c++ --with-dwarf2 --enable-target-optspace \
     --with-as=/opt/arm-elf-gcc/bin/arm-elf-as \
     --with-ld=/opt/arm-elf-gcc/bin/arm-elf-ld

I reported this problem a long time ago, but I had classified it as
an ARM problem, and it probably isn't - because I can build the 
compiler on Linux and Sun, so the bug report was ignored.

So to avoid that the bug is ignored again I post the information
here in the hope that somebody can help me supplying relevant
information.

Note that I don't have any problems building a native HPUX compiler
based on the same snapshot.

The problem first happens when xgcc is used to build thumb support
functions.

Building with 2.95.3, 20011203-snapshot or 3.0.2 on HPUX 11 all gives 
this result when building libgcc2:
