Bug#923476: webkit2gtk: FTBFS when built with parallel=1

[Santiago Vila]

close 923476 2.24.1-1
retitle 923476 webkit2gtk: FTBFS when built with parallel=1 (No rule to make target 'JavaScriptCore-4.0.gir', needed by 'WebKit2-4.0.gir')
thanks

(Note: The retitle merely adds a snippet from the build log to the title set by Alberto)

This works ok in the single-cpu systems I've tested, therefore I'm
closing this with the version in unstable.

Can we already raise this to serious, where it probably belongs?
I think it would also help for the unstable -> testing transition.

Thanks.
