During shadow-building it was noticed that executing make install
did not actually build mkv8snapshot and therefore caused an error.

Debug snapshots and release snapshots aren't compatible. Both a
debug version and release version of the mkv8snapshot tool must be
built, and the corresponding executable selected when building v8.
Adopt the library naming convention for naming the mkv8snapshot
executable ("mkv8snapshot" in release, "mkv8snapshot_debug" in debug
on Mac, "mkv8snapshotd" in debug on Windows).

A V8 snapshot is a serialized representation of the JavaScript heap.
Using a snapshot can vastly speed up V8 initialization.
This commit introduces a new tool, mkv8snapshot. mkv8snapshot is
automatically invoked as part of building QtV8, and generates a .cpp
file which is compiled into the QtV8 library.
Because mkv8snapshot itself needs to initialize the V8 environment
the non-snapshot way (i.e., by evaluating thousands of lines of
JavaScript), it needs to build all of V8. This means that V8 is
effectively built twice when snapshots are enabled.
When cross-compiling, only host=i386 and target=arm is supported,
since that's the only relevant case for which V8 currently
supports a simulator. mkv8snapshot is built and run as a host tool
(using the simulator), and generates a snapshot that will be used
on the target.
