Bug#923476: webkit2gtk: FTBFS for unknown reasons (maybe Makefile bug)

[Santiago Vila]

Package: src:webkit2gtk
Version: 2.22.0-2

Dear maintainer:

I tried to build this package in buster but it failed:

--------------------------------------------------------------------------------

I'm using sbuild + schroot + eatmydata, but the part saying

No rule to make target 'JavaScriptCore-4.0.gir', needed by 'WebKit2-4.0.gir'

suggests a Makefile bug.

I could probably prepare a VM instance in which this happens (please contact me
privately for details), but I believe a close look at the Makefile should perhaps
tell what's wrong without having to "reproduce" it.

In either case, I've put a bunch of failed build logs here for you to see:

Thanks.
