Problems building webkit-gtk

It seems that this commit may have been overzealous:

     webkit-gtk: remove no-parallel bodge

     This workaround was originally for GNU Make 3.82 which upstream was blaming
     for a parallel build failure.  Since then I've changed numerous variables
     and now parallel builds are working with 3.82 (and succeed in 20 minutes
     instead of 2 hours).

     Revert the change until we've more data about what causes the breakage, then
     we can bring it back with more finesse.

Building on my 4-way box (Core-2 duo) fails with this error:

If I rerun it, the build will succeed.

One additional question: the commit message says that this now
builds in 2 minutes?  What kind of super machines do you guys have?
I takes about 30 minutes on my (I thought fast) machine just to get
to this first break and then another 45 minutes to complete...
