It did when I tested it last, which was some weeks ago. The ctf_archive
format is fixed-endian (little-endian): everything else byteswaps at
open time if the magic number suggests it needs to, since at open time
it's reading it all in and blowing the dcache anyway and byteswapping
everything necessary costs nothing. (And means we can ignore endianness
everywhere else in the codebase.)

Note: the original CTF format (as seen on Solaris, FreeBSD etc) is
completely endian-ignorant. It looks like they never considered
endianness at all, so it's totally nonportable to machines of opposing
endianness. Whoops...
