newlib: use brk(0) to get initial program break (#172)
There are no guarantees that the break going to be located exactly
at the _end, but brk(0) is guaranteed to return its current value.
QEMU ELF loader moves the initial break up to the next page boundary,
disabling sbrk-based malloc for any allocations smaller than
the adjustment made. And ASLR may do even worse.
