If this is indeed likely the problem, let me know and I'll see if I can figure out how to fix the Makefile and submit a patch myself if I'm successful.

bfin-softfloat-elf is an invalid target. use bfin-elf. i'm not sure if newlib-1.16.0 had proper Blackfin support in it, i'll have to double check. although that may not be the problem here.

How do you know it's an invalid target? How can I learn what valid targets are? That doc would serve many readers well to explain such things. -t bfin-elf failed too by the way in pretty much the same manner.
A workaround I found on the gentoo forums: crossdev --without-headers -s1 -t bfin-softfloat-elf crossdev -t bfin-softfloat-elf Worked
i know it's a valid target because i'm one of the developers of the Blackfin architecture. softfloat makes no sense because no Blackfin has FPU support in it. some of the toolchain packages internally parse the target looking for "bfin-elf".

Anyways I'll update my configuration now that I know there are internal parts that ostensibly expect a hard coded string like "bfin-elf".
softfloat is for toolchains where the default is to assume FPU support. that is most architectures, but not the Blackfin arch. really it only makes sense on arm/mips/ppc ports.
