ghc-pkg ignores library dirs

Hi,

I'm installing several packages in sequence. The first
package specified /usr/local/lib in the library_dirs
field. The .o file is built correctly. The next package
depends on the first package. To reduce the size of the
command line of any build with the second package, I
filter out all flags that are already in the first
package. Doing this, the .o file of the second package
cannot be built since ghc-pkg does not include the
library path of the first package when it searches for
the .a file.

I think that adding only those flags that are needed in
addition to some other dependent package is a
reasonable thing to do, so I would like to see ghc-pkg
search on the library paths of all dependant packages.

Thanks,
Axel.
