Looks like a non-parallel-safe Makefile.

See
<https://ci.guix.info/log/901miwpk9srhwq3646v6bm7zni3qda8m-qtwebkit-5.212.0-alpha2>.

Interestingly this was first reported here for WebkitGTK:
<https://issues.guix.info/issue/30015>.

Did the issue vanish for WebkitGTK?  Qtwebkit is older so it may well
miss an upstream fix.

Thanks,
Ludo’.

I confirmed this hypothesis and turned off parallel builds in
b717d0f90eed10c1173ba10b30db82d502b5b9df.  Definitely not ideal, but at
least it builds reproducibly.
