Andriy Gapon 918314631b gpt/zfs boot blocks: reduce optimizing CFLAGS to -O1 
gpt and zfs boot blocks are not nearly as size-constrained as boot2
from which they inherited their current optimization and anti-optimization
options.  As such the current options do not provide any benefit, but
make debugging of the code much harder.
Also, it has been demonstrated that combination of -mrtd and
-fno-unit-at-a-time may result in mis-compilation of the boot code
with the current base gcc.

Additionally, intermediate assembly file filtering is removed for
zfsboot.

The new boot blocks are all compile- and boot- tested using qemu.
gptzfsboot is tested with real hardware.
