Implement support for chroot'ed install (aka DESTDIR)

For example:

b config.install.root=/usr config.install.chroot=/tmp/install

The difference between doing just config.install.root=/tmp/install/usr is
that everything is installed "as if" into /usr. So, for example, pkg-config
files will contain -I/usr/include, -L/usr/lib, etc.
