That would still leave the issue open that I need to manually specify

>>        -D KWSYS_LFS_WORKS=TRUE \
>>        -D KWSYS_CHAR_IS_SIGNED=TRUE \

because CMake can't find out the correct values itself.

Currently I don't, I only wanted to see if I can reproduce a binutils
issue I see on PA-RISC
(http://sourceware.org/bugzilla/show_bug.cgi?id=13168) on ARM which could
also be affected. The next thing will be that I copy the result on my
Beagleboard and test what happens.
