Subject: Implement support for dependency chains

Now instead of:

./: exe{foo}
exe{foo}: cxx{*}

We can write:

./: exe{foo}: cxx{*}

Or even:

./: exe{foo}: libue{foo}: cxx{*}

This can be combined with prerequisite-specific variables (which naturally
only apply to the last set of prerequisites in the chain):

./: exe{foo}: libue{foo}: bin.whole = false
