This patch allows to really use the core dumped by qemu with guest
architecture tools.
- it adds a missing bswap_phdr() for the program headers
of memory regions.
"objdump -x" sample:
BEFORE:
0x1000000 off 0x00200000 vaddr 0x00000400 paddr 0x00000000 align 2**21

- it doesn't pad the note size to sizeof(int32_t).
On m68k the NT_PRSTATUS note size is 154 and
must not be rounded up to 156, because this value is checked by
objdump and gdb.
"gdb" symptoms:
"warning: Couldn't find general-purpose registers in core file."
