avg 85867a4f6c 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.
