split libWebCore into two archives to avoid the 4G ar format limit

I have (on debian sid that is binutils >= 2.22 but issue should apply before those releases too)

Hi Jakub,

(In reply to comment #10)

There is also a 32-bit limit on the size of file offsets in symbol table at the start of the archive (if it has one).  This was the problem - the linker uses these file offsets to locate individual archive members and since these had been truncated when the archive symbol table was created, the linker failed to find the archive members that it wanted."

As libWebCore.a built with flags "-g -02" is 4.4G it goes beyond this limit.

I made a quick sample of how it could get fixed in attached patch (split libWebCore.a into libWebCoreA.a and libWebCoreB.a)
It is not ready to apply (the split is approximate , there is no changelog entry). It is there to open the discussion.
