Requires.private is also needed for --cflags, as the library headers for 
package foo often require the headers for bar (indeed, that's half the 
point of Requires.private).

(Of course, the recursive adding isn't done properly, but that's my pet 
bug... https://bugs.freedesktop.org/show_bug.cgi?id=8788)
