[PATCH] RISC-V: enable lui relaxation for CODE and MERGE sections.

[Kito Cheng]

Hi Illa:

I just found a case will got `relocation truncated to fit` error on
rv32 linux with this patch.

Here is the tarball for reproduce, included minimized sysroot and
necessary objects/libraries.

`make relax` can reproduce the problem and `make norelax` for disable
relax build.
