Hmm, sparc_elf/dot_init.h has .align before #entry_pt label,
but i386_elf/dot_init.h claims:
"placement of the .align _after_ the label is intentional."
What is the intention, and which should the .align be placed
for m68k_elf?

On i386, we can make gas to use NOP (0x90) for padding
by the second arg of .align. But on m68k, NOP is not one byte
instruction...
