Allow empty prerequisites in prerequisite-specific variable assignment/block
The old semantics was not very consistent, consider:
exe{foo}: cxx{$empty} # Ok.
exe{foo}: cxx{$empty}: include = false # Not ok?
So now both are ok, as well as the block variant:
exe{foo}: cxx{$empty}:
{
include = false
}
Note that the empty prerequisite list in the dependency chain is still an
error:
./: exe{$empty}: cxx{foo} # Error.
Note also that the syntactically-empty prerequisite list was and still is
an error:
exe{foo}: : include = false # Error.
