Why not use the toolchain/uClibc at blackfin.uclinux.org?

the fdpic option was deprecated, we may just not have pushed the uClibc 
changes upstream (sorry).

you should be able to follow the buildscript in our svn to see what we are 
doing.
 - build a bfin-elf toolchain
 - build multiple versions of uClibc
 - build bfin-uclinux- toolchain (for flat apps)
 - build bfin-linux-uclibc- toolchain (for fdpic)

I do this daily with the sources from blackfin.uclinux.org - and don't have a 
problem. What does the uClibc version there not support, that you want to 
build your own with?
