[Development] V8 doesn't build in cross-compilation

[simon.hausmann at nokia.com]

Snapshots should IIRC be disabled in all configs except host = target and 32-bit host to 32-bit arm (in which case mksnapshot builds the arm simulator to create the heap snapshot).

Disabled snapshots means startup penalty for v8, but no functional regression.

Turns out that v8snapshot is not necessary for building V8. So the attached 
one-line (thus, not copyrightable) patch fixes the problem.

The question still stands though: doesn't anyone try to cross-compile Qt for 
ARM these days?
