Thanks for your advise, I compile with -mrelocatable. If I remove this flag,
Error is shown:
ERROR: Your compiler doesn't generate .fixup sections!
My host gcc is gcc 4.1.2 20080704 (Red Hat 4.1.2-44),
I try different toolchain:
powerpc-unknown-linux-gnu-gcc gcc version 4.4.3 (crosstool-NG-1.6.0)
ppc_82xx-gcc gcc version 4.2.2 from ELDK
powerpc-603-linux-gnu-gcc gcc version 4.1.0 from crosstool 0.43
The problem is still there : (
