Cannot cross-compile groff-1.20.1

[booleandomain]

Hello,

I can't cross-compile groff-1.20.1 with gcc-4.4.1. Make fails with the 
following error message:

make[2]: Entering directory `/mnt/clfs/sources/groff-build/doc'
GROFF_COMMAND_PREFIX=''; export GROFF_COMMAND_PREFIX;

I think this is because the host machine is 32-bit, while the target 
machine is 64-bit, so the groff command cannot be executed. The build 
process should use the groff command from the host system, not the newly 
generated one.

Groff was configured with: --prefix=/usr --build=i686-pc-linux-gnu 
--host=x86_64-unknown-linux-gnu

My problem seems similar to that reported here:

Thanks.
