I may be wrong, but libgeneric.a is only used by U-Boot and NOT by 
examples. Examples use the U-Boot ABI which provides access to 
libgeneric.a level functions as defined by include/exports.h

Its not scary, its done through the ABI.

ppc_405-ld -g  -Ttext 0x40000 \
         -o hello_world -e hello_world hello_world.o libstubs.a \ 
  -L/lib/gcc-lib/powerpc-hardhat-linux/3.2.1 -lgcc

This is my 1.1.2 build command - there is NO generic lib linked in! It 
is NOT needed because U-Boot ABI provides those library functions.
