linux: Add sparck brk implementation

It turned that the generic implementation of brk() does not work
for sparc, since on failure kernel will just return the previous
input value without setting the conditional register.

This patches adds back a sparc32 and sparc64 implementation removed
by 720480934ab9107.

Checked on sparc64-linux-gnu and sparcv9-linux-gnu.
