Modify the library-dirs used by the rts packages to include your extra
linker search path. eg:

- library-dirs: /usr/local/lib/ghc-6.6
+ library-dirs: /usr/local/lib/ghc-6.6, /lusr/gnu/lib

First, backup ghc's package.conf file just in case...

Then:
$ ghc-pkg describe rts > rts.package.conf
$ $EDITOR rts.package.conf
$ ghc-pkg update rts.package.conf
