The .sdata and .sbss sections are created by the compiler, but were not present in the linker script. That means that the linker put them after all other data/bss section, which happens to be where the heap also resides. This commit adds the .sdata and .sbss sections to the linker script, which gets the blinky examples to work again on RISC-V.
