ctfmerge: demote "No ctf sections found" to a warning

If there are no CTF sections then ctfmerge just has nothing to do; it
should not be an error.

Note that ctfmerge has an option to require CTF:

ctfmerge: demote "No ctf sections found" to a warning

If there are no CTF sections then ctfmerge just has nothing to do; it
should not be an error.

Note that ctfmerge has an option to require CTF:
-t Make sure that all object files have a CTF section.

Before this change, this option explicitly exited without error if none
of the object files have CTF sections, with the comment:

If we're verifying that C files have CTF, it's safe to
assume that in this case, we're building only from assembly
inputs.

ctfmerge: Fix missing pthread_cond_init()

This does not appear to matter on FreeBSD or Linux, but when building an
amd64 kernel on macOS I was seeing infinite loops in ctfmerge.
It turns out the loop in wip_save_work() was looping forever due to
pthread_cond_wait() always returning -EINVAL.

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.
