[oe] STAGING_LIBDIR_NATIVE needed in bitbake.conf

[Mike (mwester)]

In order to fix an ncurses build bug
(http://bugs.openembedded.org/show_bug.cgi?id=2554), we need to set
LD_LIBRARY_PATH in the ncurses bb file.

I've tested, and the following resolves the problem with ncurses not
installing:

    export LD_LIBRARY_PATH = "${STAGING_BINDIR_NATIVE}/../lib"

That's not too elegant, so I'd like to create "STAGING_LIBDIR_NATIVE" in the
bitbake.conf file instead, which will clean up the recipe and make more
obvious what it is that we're doing.


Anyone have any heartburn with this approach to resolving this problem?

Thanks,
Mike (mwester)
