parisc: Unbreak bootloader due to gcc-7 optimizations
gcc-7 optimizes the byte-wise accesses of get_unaligned_le32() into
word-wise accesses if the 32-bit integer output_len is declared as
external. This panics then the bootloader since we don't have the
unaligned access fault trap handler installed during boot time.
Avoid this optimization by declaring output_len as byte-aligned and thus
unbreak the bootloader code.
Additionally, compile the boot code optimized for size.
