Subject: [PATCH] sh: Enable ffunction-sections and fdata-sections

Enable these two options to let compiler eliminate unused code.
On R2Dplus, this results in considerable amount of saved space:

      text    data     bss     dec     hex filename
  - 266580   13196   39076  318852   4dd84 u-boot
  + 220214   12797   38745  271756   4258c u-boot
