Revert r253678, r253661:
Fix a segfault in ctfmerge(1) due to a bug in GCC.

The change was correct and the bug real, but upstream didn't adopt it
and we want to remain in sync. When/if upstream does something about it
we can bring their version.

The bug in question was fixed in GCC 4.9 which is now the default in
FreeBSD's ports. Our native gcc-4.2, which is still in use in some Tier-2
platforms also has a workaround so no end-user should be harmed by the
revert.

Maintain target's byte order for multi-byte fields in CTF structures.

CTF format is not cross-platform by design, e.g. it is not guaranteed
that data generated by ctfconvert/ctfmerge on one architecture will
be successfuly read on another. CTF structures are saved/restored
using naive approach. Roughly it looks like:
write(fd, &ctf_struct, sizeof(ctf_struct))
read(fd, &ctf_struct, sizeof(ctf_struct))

By sheer luck memory layout of all type-related CTF structures is the same
on amd64/i386/mips32/mips64. It's different on ARM though. sparc, ia64,
powerpc, and powerpc64 were not tested. So in order to get file compatible
with dtrace on ARM it should be compiled on ARM. Alternative solution would
be to have "signatures" for every platform and ctfmerge should convert host's
reperesentation of CTF structure to target's one using "signature" as template.

This patch checks byte order of ELF files used for generating CTF record
and makes sure that byte order of data written to resulting files is the same
as target's byte order.
