im sorry, im not sure what i did wrong before...but the HAVE_LD_VERSION_SCRIPT
actually exists. 

i set it to 'no' on my environment, on the config.log it is set as:

HAVE_LD_VERSION_SCRIPT_FALSE='#'
HAVE_LD_VERSION_SCRIPT_TRUE=''

...but the build still fails on the same point.

/opt/uClinux/bfin-uclinux/bin/bfin-uclinux-nm -B

grep "^tp" < _gen/abi.funcnames > _gen/abi.tpfuncnames
make[3]: ** [_gen/abi.txt] Erro 1
