Yes parallel make is supposed to work on the current branches, there
have been many related commits over the past few years.  Note that
none of them have been ported back to 1.4, so it is not expected to
work there.

By all means post your failing build log (here or RT) when you get
errors, it's usually not too hard to figure out the problem, typically
missing dependencies or rules with multiple targets that can race each
other.  There may be things that are specific to IRIX, and in my
experience the race cases show up more easily on slower machines.  I
know that there are still some multiple targets lurking in the source,
but I've only been fixing them as I run into actual build errors.  It
might be worth cleaning the rest of them up.
