x86, boot: align the .bss section in the decompressor
Aligning the .bss section makes it trivial to use large operation sizes for moving the initialized sections and clearing the .bss. The alignment chosen (L1 cache) is somewhat arbitrary, but should be large enough to avoid all known performance traps and small enough to not cause troubles. [ Impact: trivial performance enhancement, future patch prep ] Signed-off-by: H. Peter Anvin <hpa@zytor.com>
