I just noticed that there will be a number of files missing in dh_install when
introspection is disabled. So, better not apply this fix at the moment and I
will just build webkit2gtk on ia64 manually with a patched <sys/ucontext.h>.

We will have to wait until the upstream bug in g-ir-scanner has been fixed
upstream.
