CgptManager exposes the cgpt commands via a C++ library so that
the post-installer for 32- to 64-bit upgrade can link directly
against a library and thus avoid any shell dependency.
The default make target will not build libcgpt-cc.a since it
requires some dependencies that are available only in chroot.
A separate follow-up checkin to the vboot_reference
ebuild will enable emerging the libcgpt-cc.a by default.
BUG=chromium-os:25374
TEST=Tested with the new unit tests for CgptManager,
ran existing cgpt unit tests, as well as running the
cgpt commands manually. Built on both amd64 and x86.
Tested that vboot_reference is also buildable outside of chroot.
Tested that vboot_reference-firmware and vboot_reference-tests
also build fine with these changes.
