Started making builds more dynamic

Let's use libstdc++ for now, since I'm not able to get v8 working with
the system libc++, and the embedded libc++ that comes with v8 doesn't
play well with caf for some reason.

probably due to embedding the wrong .o file from mksnapshot

proper permissions to access certain files for packaging.

This flag should mangle as such:

ld: error: undefined symbol: v8::platform::NewDefaultPlatform(int,
v8::platform::IdleTaskSupport, v8::platform::InProcessStackDumping,
std::unique_ptr<v8::TracingController,
std::default_delete<v8::TracingController> >)

Instead of: (note the std::__Cr:: instead of std::)

000000000000f5e0 T v8::platform::NewDefaultPlatform(int,
v8::platform::IdleTaskSupport, v8::platform::InProcessStackDumping,
std::__Cr::unique_ptr<v8::TracingController,
std::__Cr::default_delete<v8::TracingController> >)

use the monolith build thing that's part of v8. In theory that should
do the right thing already.

Should be related to the following runtime issue:

 #
 # Fatal error in , line 0
 # Failed to deserialize the V8 snapshot blob. This can mean that the
 snapshot blob file is corrupted or missing.
 #
 #
 #
 #FailureMessage Object: 0x7f40ed7b8230

This will also require a bunch of fixes in Starcry.

Add packaging for v8pp
