Hi Huacai and Arnd,

The old toolchain will use

    R_LARCH_PUSH_PCREL _GLOBAL_OFFSET_TABLE_
    R_LARCH_PUSH_GPREL symbol
    R_LARCH_ADD

to perform a PC-relative addressing for a GOT entry, and the new
toolchain will use R_LARCH_GOT_PC_{HI20,LO12}.  Both way are supported
by this series.

I've tested the V3 patch (V2 + suggestions from Youling, I'll sent it
later after rewording the third patch) with both my system toolchain (no
new reloc support) and a toolchain built from binutils & gcc master. 
Both of the build works fine.

So a toolchain update seems not immediately required.
