[PATCH] ncurses-native: install to libdir, not base_libdir

[PATCH] ncurses-native: install to libdir, not base_libdir

[Christopher Larson]

From: Christopher Larson <chris_larson@mentor.com>

For target, both base_libdir and libdir in sysroot can be used, as we pass
--sysroot to the toolchain. For native, we don't do this, and we also only add
-L<sysroot>/${libdir}, not -L<sysroot>/${base_libdir}, resulting in other
native recipes (like readline-native) failing to find the ncurses libraries.

readline-native only built successfully on hosts where it could fall back to
their ncurses/termcap rather than the one in the sysroot.

Fixes issues I'm seeing while rebuilding from scratch, thanks!

I do not think that this should be done per recipe (afais, at least
libusb is affected by the same issue).

Adding '-L<baselibdir>' and the '-Wl,-rpath-link' + '-Wl,-rpath' options
to BUILD_LDFLAGS would be a more general solution.

Alternatively, could simplify the layout of the native sysroot and
adjust things in the native class. It could make a certain amount of
sense, as it makes more sense for our structure for native to match
the host than it does the target.

So, Chris, are you going to implement this and do we drop the ncurses 
patch for now?

Sau!

We need to merge something to resolve this issue sooner rather than 
later, I had to apply this change in order to build on a system without 
ncurses installed.

Enrico sent his general change in a patch series already. Someone will
need to make the call on the preferred long term solution.

Merged into OE-Core along with Enrico's Patch.
