Both are valid. config.guess guesses (sic) the complete name
of your target with what you gave, along with some assumptions.
For example, *-linux targets will normally be elf, but you can
have a.out if you ask for it (a.out and elf are two different
executable format, somewhat like .com and .exe under Windows).

Good question which I don't think has an answer; or if it
does, I don't know it :-)

The general rule of thumb is that if you don't know what something
is, then you don't want/need it. Eg: if you don't know an ARM is
a processor, you most probably don't want to compile anything
for it :-)
elf and coff are 2 executable formats.
