[Bug c/31798] New: lib1funcs.asm:1000: undefined reference to `raise'

[kletschke at synertronixx dot de]

I have a toolcahin working quite well: gcc-4.1.2 binutils-2.17, generic
arm softfloat supporting EABI. This works with kernel and userspace
well. Only on u-boot it fails at the final stage:

undefined reference to `raise'
make: *** [u-boot] Error 1

Well, compiling u-boot works fine with another arch (pxa xscale), only my arm9 
i.MX arch triggers a bug here. Does somebody have an advise or tip for
me how to fix this?

I digged around and added an (empty) raise() function to my u-boot, which
compiles fine. 

Kind Regards, Konsti
